Recently i passed through knol which is from Google they simply call it as unit of knowledge .I used to read knols regularly because various important and useful things are provided in knols.So here is introduction about knol
A knol is an introductory article about a specific subject. To write a successful knol, focus on the first things a reader would want to know about your topic. Remember that knols are openly available online, so you should aim to write for the broadest possible audience. For example, it’s best to avoid jargon and explain technical terms in straightforward language.
So just whenever you have time just grab a knol it simply we can say grab knowledge
Google Social Search is a feature designed to help you discover relevant publicly-accessible content from your social circle, a set of online friends and contacts. The idea is that content from your friends and social contacts is often more relevant to you than content from strangers. For example, a movie review from an expert is useful, but a movie review from your best friend can be even better.
What is there in the social search or what type of content it provides
If you’re signed in to Google, you might see social search results for a particular search at the bottom of the results page under “Results from people in your social circle.” All the content shown within Social Search is publicly-available online through Google and other search engines. Social Search simply highlights content from your social circle to provide a personalized search experience.
Here are some of the types of content you might see:
Websites, blogs, public profiles, and other content linked from your friends’ Google profiles
Web content, such as status updates, tweets, and reviews, from social services that your friends have listed in their Google profiles
Images posted publicly from your social circle on Picasa Web and from websites linked from their Google profiles
Relevant articles from your Google Reader subscriptions
See a list of your social circle connections at google.com/s2/search/social. That page shows your direct connections, secondary connections (friends-of-friends), and some of the content that each of those connections has published publicly to the web. You can also reach this page by clicking the link next to “Results from people in your social circle” on any Google search results page that’s showing social search results.

Google supports mRSS, an RSS module that supplements the element capabilities of RSS 2.0 to allow for more robust media syndication. If you publish an mRSS feed for the video content on your site, you can submit the feed’s URL as a Sitemap. For detailed information on creating an mRSS feed, including samples and best practices, please see the Media RSS specification. Google also supports RSS 2.0 using enclosures tags for video content and thumbnail urls.
A Video Sitemap uses the Sitemap protocol, with additional Video-specific tags as defined below. In its simplest form, a Video Sitemap must include a link to a landing page for a video as well as some essential information required for indexing the video. While several fields in the Sitemap are optional, they provide useful metadata that can improve our ability to include your video in search results. Google may use text available on your video’s page rather than the text you supply in the Video Sitemap, if this differs.
Once you have created your video Sitemap, you can submit it to Google using Webmaster Tools. While a Video Sitemap helps Google find content on your site that we might not otherwise discover, we don’t guarantee that all videos included in a Sitemap will appear in our search results, or that we will use all the information included in your Video Sitemap.
Here is a sample of a Video Sitemap entry using Video-specific tags:
<urlset xmlns=”http://www.sitemaps.org/schemas/sitemap/0.9″

Video-specific tag definitions
Tag
Required?
Description
<loc>
Required
The tag specifies the landing page (aka play page, referrer page) for the video. When a user clicks on a video result on a search results page, they will be sent to this landing page. Must be a unique URL.
<video:video>
Required
<video:player_loc>
Required
At least one of <video:player_loc> and <video:content_loc> is required. A URL pointing to a flash player for a specific video. In general, this is the information in the “src” element of an <embed> tag and should not be the same as the <loc> tag.
The required attribute allow_embed specifies whether Google can embed the video in search results. Allowed values are “Yes” or “No”.
The optional attribute autoplay has a user-defined string (in the example above, ap=1) that Google may append (if appropriate) to the flashvars parameter to enable autoplay of the video. For example: <embed src="http://www.site.com/videoplayer.swf?video=123" autoplay="ap=1"/>.
At least one of <video:player_loc> and <video:content_loc> is required. This should be a .mpg, .mpeg, .mp4, .mov, .wmv, .asf, .avi, .ra, .ram, .rm, .flv, or other video file format, and can be omitted if <video:player_loc> is specified.
<video:thumbnail_loc>
Required
A URL pointing to the URL for the video thumbnail image file. We can accept most image sizes/types but recommend your thumbs are at least 160×120 in .jpg, .png, or. gif formats.
<video:title>
Required
The title of the video. Limited to 100 characters.
The description of the video. Descriptions longer than 2048 characters will be truncated.
<video:rating>
Optional
The rating of the video. The value must be float number in the range 0.0-5.0.
<video:view_count>
Optional
The number of times the video has been viewed
<video:publication_date>
Optional
The date the video was first published, in W3C format. Acceptable values are complete date (YYYY-MM-DD) and complete date plus hours, minutes and seconds (YYYY-MM-DDThh:mm:ss). Fraction and time zone suffixes are optional. For example, 2007-07-16T19:20:30+08:00.
<video:tag>
Optional
A tag associated with the video. Tags are generally very short descriptions of key concepts associated with a video or piece of content. A single video could have several tags, although it might belong to only one category. For example, a video about grilling food may belong in the Grilling category, but could be tagged “steak”, “meat”, “summer”, and “outdoor”. Create a new <video:tag> element for each tag associated with a video. A maximum of 32 tags is permitted.
<video:category>
Optional
The video’s category. For example, cooking. The value should be a string no longer than 256 characters. In general, categories are broad groupings of content by subject. Usually a video will belong to a single category. For example, a site about cooking could have categories for Broiling, Baking, and Grilling
<video:family_friendly>
Optional
“No” if the video should be available only to users with SafeSearch turned off.
<video:duration>
Optional
The duration of the video in seconds. Value must be between 0 and 28800 (8 hours). Non-digit characters are disallowed.
<video:expiration_date>
Optional
The date after which the video will no longer be available, in W3C format. Acceptable values are complete date (YYYY-MM-DD) and complete date plus hours, minutes and seconds (YYYY-MM-DDThh:mm:ss). Fraction and time zone suffixes are optional. For example, 2007-07-16T19:20:30+08:00.
When creating your Video Sitemap, keep in mind the following:
A Video Sitemap should contain only URLs that refer to video content. Video content includes web pages which embed video, URLs to players for video, or the URLs of raw video content hosted on your site. If Google cannot discover video content at the URLs you provide, those records will be ignored by Googlebot.
Since each video is uniquely identified by its content URL (the location of the actual video file) or, if a content URL is not present, a player URL (a URL pointing to a player for the video), you must include either the <video:player_loc> or <video:content_loc> tags. If these tags are omitted and we can’t find this information, we’ll be unable to index your video.
Each Sitemap file that you provide must have no more than 10,000 video items and must be no larger than 10MB uncompressed. An individual video file or thumbnail (specified in the <video:content_loc> and <video:thumbnail_loc> tags, respectively) can be no larger than 30MB. If you have more than 10,000 videos, you can submit multiple Sitemaps and a Sitemap index file.
Google can crawl the following video file types: .mpg, .mpeg, .mp4, .mov, .wmv, .asf, .avi, .ra, .ram, .rm, .flv. All files must be accessible via HTTP. Metafiles that require a download of the source via streaming protocols are not supported.
The URLs included in the Sitemap must have their robots.txt file set appropriately for User-agent “Googlebot”.
If you have multiple videos embedded on the same html page, use separate <video:video> entries for them with different <video:player_loc> or <video:content_loc> information.
Google web crawlers will verify that the information you include in the <video:title> and <video:description> fields matches your live site. You should view your play pages in a browser such as Lynx to make sure Googlebot will be able to find them.

Google Wave is an online tool for real-time communication and collaboration. A wave can be both a conversation
and a document where people can discuss and work together using richly formatted text, photos, videos, maps, and more.
googlewave
What is a wave?
A wave is equal parts conversation and document. People can communicate and work together with richly formatted text, photos, videos, maps, and more.
A wave is shared. Any participant can reply anywhere in the message, edit the content and add participants at any point in the process. Then playback lets anyone rewind the wave to see who said what and when.
A wave is live. With live transmission as you type, participants on a wave can have faster conversations, see edits and interact with extensions in real-time.
