Twitter Search Engines
Did you know you can search Twitter posts without having a Twitter account? Try Twitter search (http://search.twitter.com) or a new search service, Twazzup (http://twazzup.com). For monitoring multiple Twitter searches in real time, try Twitterfall (http://www.twitterfall.com). All of these services use Twitter search commands; for a list, see http://search.twitter.com/operators. All are free and do not require a Twitter account. If you try any of these, leave a comment and let us know how it worked for you!
