Yes I was, but the discussion pages seem less conductive to actual discussions then here where threaded conversations are easy to conduct.

In addition, I had the impression, with little evidence, that it would be inappropriate to put personal observation into the wiki. Which can be confirmed on the wiki main page: "This wiki is not for original research - that is, it is not for directly discussing topics or concepts that have never been discussed on the blog." The idea I took away from this is that there should be some sense of consensus before adding topics/ideas to the wiki and this seems to be the place where that happens.
