Well its too bad to have it fragmented the way you mention. I dont think its bad to have a release site and then a support site, as long as it is known and purposely set up that way.
Stuff like this can make people nervous because they will think their app won't be supported any more, and that's no good.
Off topic, in order to keep the support posts to a minimum, preventing dupes, the Knowledge Base HAS to be put together in a easy to use, easy to read, way or things are gonna get out of hand. Just MHO.
