So we have a walled garden network fucking over its users, and you think the solution is to replace it with another walled garden because its rulers are supposedly more benevolent? That's not very ambitious. Think bigger. StatusNet/Identica is free, open source, and (most importantly) federated.
No, i actually think just he's correct. It's OK to be wrong though, so no big deal.
Though I do disagree with his sentiment. I think App.Net is a perfectly good alternative to Twitter and every attempt at open, federated services since the original one (eg www) have failed to catch-on.
