Twitter is just another social site like Facebook. While Twitter is kind of like a status updater, it can be used for MANY other things. You can have conversations with people (Like an IM). You can promote your website, blog, band or whatever. You can connect it to a lot of other sites online so that you can update your followers of whatever you do on that site. Twitter is a whole other world. So if you want to connect & meet new people, you should definitely get a Twitter account as well.
