Social media searchers have another tool in Social Mention (http://www.socialmention.com/). Social Mention has tabs for searching blogs, mico-blogs, bookmarks, comments, events, images, news and videos. They search web properties such as: Google blog search, Twitter, Delicious, FriendFeed, Flickr, Digg, YouTube and many others. Searching is via a simple search box, and advanced search options are available. Of particular interest is the availability of an API; media monitoring companies may be able to tap into Social Mention's database to search for further analysis.

Overall, this could develop into a good tool; I'd like to see a search option that combines all of the tabs.
