Costolo and Ev are dickish enough you expect crap from them, but Dorsey used to have some hacker cool. I wonder if either Dorsey doesn't have enough power to swing Twitter back to being open and cool again, or if he's drunk the rich and famous Koolaid to the point he just wants to cash out in a big IPO and doesn't care about the things he used to care about.
Regrettably companies trying to squeeze enough revenue out of "free" Internet services to have a successful IPO are pretty much compelled to be complete dicks, so its probably gonna happen.
It just kind of sucks that Twitter is the absolute coolest news stream there is, there aren't any good replacements and you KNOW they are going to totally wreck it by the time they IPO or within a year of going public and we are going to all have to start over on some new "never heard of" clone. Then repeat cycle endlessly every few years. Dave Winer will keep shouting to use RSS but RSS completely sucks by comparison.
As an aside a few days ago I read New Yorker and some other mags were getting weary of letting Flipbook scrape their content and were going to just put a lead in and link users to their main web site through flipbook instead. I'm thinking, wow that's what Twitter was already doing. I totally never understood what Flipbook offered to justify the hype. A good Twitter stream in a good client is infinitely better.
The only reason I don't use it more regularly is that they don't have a proper API yet and therefore have no apps for my blackberry.
