Tweetaboogle is an interesting mashup of Google and Twitter in a Facebook-like interface. Just carry out a regular web, news, video or image search, and the Google results are given context by any related tweets that the site has uncovered.

You could then click your preferred Google link; maybe you'll be inspired by the tweets to carry out another search; or you might even add a tweet of your own (anonymously, if you like) - it's your call.
