what do people search twitter for? back when google used to insert live twitter results for particular web searches, the comments were always silly and not useful. i've only done it a few times from search.twitter.com to check if anyone else was complaining about a particular service being down. in those instances i didn't really care what the people were saying, i just wanted to see if there was any recent activity about it.
