I have searched to see if there was any post about this but the only thing I could find was this answer explaining what Meta is, and it still suggests that Meta is supposed to be used for asking questions, not advertising new features or announcing new community managers.
For example, how is this a question?
Why should someone get 1460 (292*5) points for "asking" it?
We then have people getting 530 (53*10) points just for saying congratulations and nothing else:
Furthermore, and perhaps of most importance, why do we only let these free points for people saying things like "congratulations" go to people that already have 10 points reputation (see image below)?
