I'm pretty sure Twitter is "guaranteed delivery", but thats just my naive user expectation.

Poking, while needing to be reliable is a 1:1 activity, so light on writes and easy to read, whereas broadcasting is difficult because of the wide variance in update frequency and number of followers from user to user.
