I had read about Twitter when Casey first wrote about it, and later his critisism of it, but I didn’t have much interest in it at the time. Adam started using it it earnest last week and after hearing about it on Fair Game on Friday night I decided to give it a shot. So far I haven’t had too much of a chance to play around with it. I am having some trouble with the IM integration, “TwitterIM is under maintenance at the moment. Please check back later.” which I understand, but when trying to enable updates via my mobile phone I just get an “Invalid Address” message, which gives me much less to go on.
