Fresh from Microsoft’s Research Group comes a new IE7 plug-in called SearchTogether, which lets you browse the web with your friends. With SearchTogether, groups can chat while they search and annotate the results with comments and ratings via a thumbs up / thumbs down button. The plug-in can also be used to do “split searching,” which is when a set of search results is split among the team, with each user working on a subset of the results. All the activity – chat, queries, comments, and ratings – are saved so that group members can later return to the search session and view the results. If you want to try SearchTogether, you can download the plug-in from here.
