Coming from SO, and majoring in quantitative finance, I have spent the past day reading through some of the awesome questions/answers in this community. I feel as though there are a couple canonical questions however that, while directly relating to quants, have yet to be asked or canonically addressed on the site. I know that on SO or MSE for instance, self-answered questions can be encouraged if they provide value, so I was wondering if the younger community here has any admonitions against them (should they be great questions/answers, of course).
I think there is no restriction about self-answering.
It is not so common in quant.SE, but sometimes users self-answer to their own question and nobody prohibited that behavior or something like that.
Of course, wait for some answer given by some older and more expert user than me! :)
