<p>In answer to Glen_b, I think the site management is outstanding. It seems however that the group of users who have questions but cannot answer any is much larger than the group of people who can answer questions (and may have some own ones once in a while). Related, statistics as a field is rather wide, the number of potential applications is huge, and the scope of both is growing rapidly, especially with adjacent fields like ML being integrated. So it may be harder for CV to maintain a critical number of experts with wide enough joint knowledge (and time) to provide a sufficient amount of answers.</p>

<p>Two further factors may also play for some people and I have seen them being discussed here on meta CV before. First I believe CV has a rather disastrous upvoting problem. I have seen questions with five answers while the question did not have any upvote, nor the answers. In my humble opinion, if you answer a question it probably was good enough to deserve an upvote. If somebody takes the time to answer your question, you should upvote it (nearly) regardless of the quality (nearly = except if wrong, off topic etc., see comments below). Whether an answer is great is decided by the community by giving even more upvotes.</p>

<p>Second, I have caught myself not giving an answer to newbies because in 90% of the cases you never hear from them again (again no upvote but also no accepted answer). I suspect the upsurge in questions is related to an instream of new users. So potentially more experienced users may be discouraged from answering these questions by earlier experiences of this kind.</p>
