Well, yes. When discussing code I am mainly interested in talking to coders who actually want to make use of the code, not bystanders who are just looking for debating practice. Seems kind of obvious. Or at least I would have thought.
As for building a community, I think we're doing fine. 50 new QA volunteers in the last two weeks, based on a promotion that I took the lead on. Coders will be next.
In any case, don't feel that you absolutely need to respond unless you have a comment on the article. I'm happy to answer questions on those topics. But I'm not going to waste time engaging in meta-arguments, i.e., arguments about the argument, by those who have nothing useful to say about the main points of the article.
