Just wondering whether Google Reader is gradually evolving into a Social Networking Site? It has now improved its Sharing options. It has become easier to share your favorite sites with your friends. It provides for a “Note in Reader” link that can be dragged and dropped in your browser’s bookmarks bar. Once that is done, you are ready to share your favorite sites or the sites you just discovered. Select a relevant portion of the site you wish to share through Google Reader and click on “Note in Reader”. (Well text selection is optional, but it is also better to be focused). A window will open up with title of the site being shared with selected text already filled. Now just put your annotation (yet another optional step) about the site (your friends might like to know as why you are sharing?) and click “Post Item”. You have now shared an item through Google Reader. You can email the links of shared items to your friends, share through your blog (ready to add clip in Blogger available) or copy and paste relevant HTML snippet in your site.Will Google Reader continue to add such features and evolve into a Social Networking Site? It can add profiles, favorite contacts, communities, pictures and all that stuff. With all these usual social networking stuff powered with shared knowledge (sites), Google Reader could become “Google Wisdom” for a participating virtual community.
