I'm a big fan
of the development blog. As often happens with well thought out articles, usually there's little if nothing to add. That certainly doesn't mean that the effort isn't appreciated.
I have thought, though, that aside from the "comment" function, for each development blog entry there should be a corresponding topic added to the forum automatically, if there isn't one already. Perhaps the forum could have a "development blog" section of its own, I don't know. I haven't really thought this through.
The "comment" part, as I see it, would serve its function as being very strictly on the subject, whereas in the forum the discussion could embrace larger spheres if need be.
