I know what you guys are going through, and I feel your annoyance, but isn't that the whole point of opening an app that requires an active internet connection to work? Why would I launch my twitter app if I don't intend to tweet or read the latest tweets from my friends? If I wanted to read old tweets, I wouldn't even bother using the twitter app, since I can read them from my events screen anyway.

IMHO, this isn't a bug. It's more of a subjective inconvenience.
