Yeah Stuart, Friendfeed is rapidly growing on me. Did I say I was stunned by the speed? :) I guess these ex-Google engineers at Friendfeed know their stuff.
Yeah twitter is horribly broken at the moment and it is going to start costing them. I'm playing with Friendfeed right now and the speed is just stunning. They need to get IM and SMS integration, then they'll be rocking.
It's really hard to say... I just dislike the idea :) I can understand Silverlight for running rich apps in the browser, but why should I need another API/Framework for running desktop apps?
