While I've yet to crack the 10k threshold of rep, I still have a reasonable amount. And, I've never asked a questionI've never asked a question on SO. So those are my qualifications. Yay me.
Anyway, I just don't think about asking questions. I'm used to finding an answer to a problem quickly (be it on SO or some other place), and I just don't think about doing the old ask-myself-a-question deal. I answer questions while I'm processing a cube or waiting for a query to run, so by and large, I'm not really in a question-askin' mood when browsing SO.
Moreover, I work with really, really bright people. They tend to point me in the right direction on difficult problems more than not. So, that conversation happens offline, completely away from the realm of SO. Therefore, I'm not thinking about it when I'm on SO, and so I don't post it.
I highly suspect that one of these days I'll come across a problem that I can't get answered with my usual begging, pleading, and Googling. On that day, I'll ask a question. Until then, I'll keep answering when I can.
