@Kaestur: It's not a matter of how effective the moderation tools are. It has to do with how effective the moderators are in establishing a certain level of quality. You can't "trust the community" when the majority of people in that community are lazy highschoolers and crackpots (i.e. the "wider mathematical community").
As far as I remember, MO has never had a "flood" of crackpots. We've sporadically had some trolls. To the extent that we had any problem users, most of the work was done by high-rep users using their high-rep privileges: downvote posts, flag posts, close questions. The software makes aggressive moderation pretty easy once a core of high-rep users develops.

Yes, this is the most important point I've heard made.
In particular, it got a lot easier around here once there was a core of 3000+ rep users to close questions. Fortunately, the era in MO's history before that happened was also the era where we didn't have enough publicity to really attract a lot of problem users; most people got here, I imagine, through a combination of blogs and word of mouth. MU will likely have bigger problems in this regard, since my guess is its userbase will grow much faster than ours did.
Yes, but Justin L is among the top-ranked users on MU, so the sword cuts both ways, Akhil.
The public beta has just begun!
Just took a look at the public beta. I think things are looking really good over there!
I think MU is looking pretty good; I would definitely encourage users here to answer questions there and maybe seed some more elementary questions while they're at it.
Also, shameless plug: vote up my suggestion for the domain name! I think it's catchy, anyway.
Could everyone here please vote for the name "mathunderflow"? It is much better than the trite and boring "mathexchange" or the odious "dividebyzero.com", which has, in a stunning display of lack of imagination reached the top of the list.
I can't vote because I don't have enough reputation. I don't like MathUnderflow for precisely the reason that Michael Lugo gives ('This name gives too much of an impression that this site is for people who "aren't good enough" for MathOverflow').
I agree that DivideByZero is rather terrible.
I also don't know what AxiomFive could possibly be referring to. The parallel postulate?
I think it's the axiom of comprehension of Frege. However, how can one seriously expect people today to remember the numbering of the axioms of a specific exposition of naive set theory from over a hundred years ago?
