The most interesting thing about Twitterrific is that it isn’t an application. At least not in the traditional sense. The Twitterrific window floats above everything else in a semi-transparent state and has no menu bar. So it is very useful for people who don’t want a Twitter application at all, but want it to be part of their desktop.
Beyond that it shows your recent incoming tweets and that’s it. So it is missing deep functionality, but it may be more suitable for simply keeping up with what is going on.
