Earlier quoted context omitted.
Admiring's fine, it's criticizing that I have a problem with. It takes all of half a second to say "Twitter stability sucks," but it takes a LOT more work to actually make a Twitter that is stable. Anyone can say what's wrong with the world.
Criticizing, too, is important. Without it, Twitter's stability would never improve. Hell, even with it, it seems unlikely to happen.
Bad Twitter stability will get fixed if and when it translates into lost revenue and/or market share. From what I have been reading, it already is (apparently to FriendFeed if I remember correctly. I am not at all into the Twitter thing, so please correct me if I'm wrong).
These are businesses. Profits, market share, revenues, that kind of thing matters. Everything else matters only when it translates into something that matters.
