You really need to chill, dude. The past is the past and cannot be changed.
OK 4.0 should have been called "4.0 Developer Release/Foundations" or something, but other than that it was OK to release. That would have made the "KDE 4.0 is not KDE4" excuse more understandable.
But it did work and the libs were done. You cannot wait for 10 years to be totally perfect (just look at E17 ... that does obviously not work)
It had a lot of missing features and very few ported apps but people were able to use it productively AND IT WAS A GREAT STARTING POINT! (just look at 4.2 now)
1. Don't just call a release that mostly/only sets new foundations "$X+1.0" or people will whine for YEARS (like you do)
2. If you don't want distros to ship your stuff without fall back solutions make that very clear (mostly to Fedora devs)
3. Provide the OGG links for your blip.tv videos because then nobody can complain about a nearly perfect release [anouncement] (4.2)
Did I miss something?
I hope people will read this post before KDE 5.0 based on Qt5 is released ;)
