I was looking for Perl bindings for Wt as well. Any progress in that direction? Or can you point me to the discussions with the developers that you've had already?

As of June 2011, this article is painfully misguided. All of Joel's anarchic rules are nowadays ignored, given the massive increase in vandalism and spam. (Right now, the two comments above mine are spam). I'm a member on both flat forums (xda-developers, notebookreview) and threaded ones (reddit, slashdot). For the same number of posts in a thread, say 200, I rarely manage to read an entire thread on the flat forums, because the posts are so disjointed. With threads, if a thread goes in a direction you're not interested, you can ignore that, and go to another branch. With a flat forum, you have to read or skim until the conversation goes back to what interests you. I'm not saying it goes off-topic, and that a new thread was started; no, it's just that you are not interested in that direction. Finally, it should be pointed out that more and more commenting systems (Disqus being a large example) are threaded. In my opinion, flat forums had a headstart, but it's an implementation that lacks vision.
