Our answered rate is plummeting more and more obviously. I had trouble coming up with explanation, until I discovered in extended stats one metric that seems to correlate with it - how many new active users had appeared on site in last two weeks.
We seem to be terrible at this. Closest site in stats (Tex) has acquired over four times more new active users in same period. Many sites with much lower activity acquired more (in some cases a lot more) active users.
Drupal and Sharepoint seem to hint at similar dynamic, but they are newer sites and probably hadn't reached a tipping points when user base starts to grow rapidly (as it seems to for us).
I blame general situation in larger WP ecosystem. As we all know demand is insane (and rising) and I don't think I've ever heard about remotely competent WP developer lacking things to work on (heck, if I pass for remotely competent WP developer nowadays :) So proportion of demand to expertise is far from favorable for satisfying demand.
Question is - can we deal with this in context of WPSE and if so then how?
