Random post – I just installed Thwirl on my PC side on my macbook so that I could use that to post to twitter while at Educause 2008, rather than via the Yoono sidebar extension on firefox, which I have installed on the mac side.
There is a solid 20 second gap between when tweets show up on Yoono vs. Thwirl. The latter is much slower. Very weird. And unfortunate.
