That being the case, it is good to point out that my Tw subchannels, like #PSC1121grav, can be read from a search like this
http://twitter.com/#search?q=psc1121gravand then saved in my Tw page's right hand sidebar.
Just a suggestion. I cannot claim this is the best.
But if you use a Tw application, I would like to hear about how it works and why you like it. Post your remarks in Discussions.
