It's my first Beta phase on a SE and i am not very long on the whole network.
I noticed that many Questions on the Meta Page are phrased like "are we doing this" or "should we accept this" even "do we want - that kind of question - to be on Topic".
This type of questions are mainly opinion based. So should there even be an Selected Answer? After this short Time (not even 50 views on the Questions) the usual 10 Members on the Meta Page responded to the answer and than their Opinion is set there. Mostly looking like this is now set in stone.
IMO the Answers should at least be locked for a week so everyone has the time to UP and DOWN vote and than the questioner can select one answer.
