TwitDir is a latest service related to Twitter. Simply put, according to the official description, it's a Twitter dictionary. With TwitDir, you can search for users on Twitter. Of course, the principle is still keyword matching, so try to use accurate spelling to search for users. With the rise of Twitter, related services are emerging one after another. However, my Twitter account has basically been unused. I also can't get interested in similar domestic services. Maybe it's because I don't like to come out and chatter when there's nothing to do. I'd rather write some blogs honestly.
