I think it's worth pointing out that the purpose of a Beta period is to get the bugs out of something. That part in the FAQ about "earning a living at this", present tense, is probably a bug. Much of the rest of the FAQ is built on that foundation.
In a previous life, I was a derivatives systems engineer, escaping from NYC after making VP. These days I'm just me, trading my own account, running a business, and pursuing a continuing education in what is today being called QF. I can think of quite a few people I worked with, pretty smart researchers and developers, who certainly left not long after me if they wanted to preserve their sanity, and who are probably doing about the same thing as me today. People like that have a lot of insight, perspective, and interest, and for once in their life they have the time to contribute and are no longer fettered by IP issues. But according to the FAQ, neither they nor I should be here. You're chasing away some of your most experienced potential contributors.
You're also chasing away your own future. Why, in the name of all that is holy, would you want to bar aspiring professionals? Any normal professional organization does everything they can to attract, encourage, and nurture new entrants into the field -- if they don't, the organization doesn't usually do so well. But Quant.SE's FAQ actively discourages them, considers them to be "outside the industry", and says questions from them are "totally off-topic and will be closed". Pretty harsh.
I would participate more if it weren't for the fact that I don't want to waste my time, and anyone else's, posting something that could be closed as off-topic, even as it's accumulating well-reasoned answers from interested readers. I see this pattern repeated over and over on Quant.SE. Sure, the silly "how do I make money trading stocks" questions are completely out of place here, but a healthy community needs to have an intergenerational makeup, and the current FAQ, as worded, tries pretty hard to keep that from developing.
Edit: Just realized, on re-reading, that I probably sound a little harsh myself -- must have been having trading floor flashbacks. ;-) Seriously, I've been watching Quant.SE's slow progress for many months now, and hoping it would pick up a bit. I was a brand-new participant on Economics.SE, was glad to have found it -- just before it shut down. I think Quant.SE might be past the risk of that happening, but I do hate to see a community stifle its own growth potential.
