Besides the Village pump and article-related talk pages, there are other ways to talk to Wikipedians. The English IRC channel is quite popular, regularly reaching up to 300 users. If you care about our policies and general Wikimedia-related matters, you may also want to consider subscribing to one of the mailing lists (high traffic!).
