There is no where on the KDE website to inform users that the .0 is not totally complete (I use that in the sense of stable and not obviously meaning the perfect DE) and that if they want the more stable releease to wait for .1 or even a .0.x release, because the parties they had to celebrate the release (and they are entitled to do so as they worked very hard) will attract people such as digg/slashdot users and mainstream reviewers.
Oh, that was you point..
I agree completely. Though there are more version numbering schemes there is software (open source or otherwise), it is pretty lame to call something 4.0 with no alpha, beta, or rc if you know it's not ready for the general public.
