Witter is not complex and is the best thing out there, though there are any number of attractive web-based options. Witter has lately gone a bit pants, as someone commented (what does it mean, anyway?) but that's because its developer is ceaselessly curious and trying to find better ways to do things. We're lucky to have him.

What Witter really lacks is a way of saving searches, like Twitter au naturale has. But many of the other frequently praised apps don't even HAVE a way to search, which is disgusting, unacceptable, and the developers should be shot. (well, maybe I'm going a bit overboard <g>)
