Crad, thanks for your time. My goal isn't to replace twitter clients - but to offer a place one checks from time to time to get caught-up and possibly discover interesting tweets which were simply lost in the noise.

BTW, do you rely on the use of "lists" to keep up with "who is saying what"? Or do you simple resign that to a serendipitous event? I think this is what most people do. Another problem I'm trying to solve...

I find this "experiment" interesting because doing it well has widespread application and benefits.
