Hi Kevinjohn,

First, I'm always up for having someone playing Devil's Advocate! :) But I should note: I've actually got another comment held in the moderation queue (too many reference links), in which I compare WordPress and Joomla, with respect to Community Gatherings, Community-Contributed Extensions, Official Support Forums, and Community-Contributed Documentation. I merely left off the StackExchange comparison, and posted a follow-up comment - which currently appears rather out of context.

Second: the premise primarily entailed not the quality of the help provided by the community, but rather by the relative size of the community. The assertion that WordPress has a small community relative to Joomla or Drupal is prime facie absurd.

The relative quality of help provided by each community is another question entirely, and one that I wasn't really attempting to address. But, to that point:

In my experience, finding out answers to simple WP questions is very quick; but rises at an exponential rate as you move from simple to moderate to advanced. In large part due to the input/output of it’s community.

That's actually what prompted me to mention StackExchange. The relative difficulty of a typical WPSE question is considerably more advanced/complex than the typical WPORG support forum question - and in my experience, the answers are commensurately advanced and thorough.

(Although, I would also counter that the problem with the WPORG support forums isn't the quality of answers, but rather the quality of the original questions; people simply fail to follow instructions - instructions designed to help them get the best-possible answers to their questions. That is, in part, why I believe that WPSE is uniquely designed to help get answers to the more difficult WordPress-related questions.)
