Twitterific is terrific, but I couldn’t figure out how to send direct tweets. Turns out Control-D does the trick. they really should connect Twitter to IM networks for longer discussions. Twitter is fun but it’s rapidly approaching it’s max usefulness with such a limited set of functionality. I grok that simplicity in design and functionality was part of the original idea but following 100 people? Time for some ambigious Facebook-style privacy control controls. Have you seen those sliders? Ridiculous.
