I think the problem is that people (partially those directly involved in the project and partially those that 'heard' about the project) post too early (and too much 'wishful thinking') about it. That and the fact that it happened too often create those seemingly negative reactions which are frankly just a result of experience with those announcements.
That said both bumping old threads for the sake of showing support without any news and nay-saying doesn't help
A lot of threads got scratched from the bottom of the board because Elbox announced a new accelerator and the ACA500 is finally available. Let's please just talk in those threads for now and give old projects the benefit of doubt 'until further notice'
