Heh, but I beg to differ, and I'm not a wilting flower when it comes to using bleeding edge stuff.
Some problems are bad, some problems are good.
KDE had(s) the problem where people want to use their stuff. They like the ideas, the applications, the way things work.
I suspect the distributions wouldn't have paid any attention to 'improved communication' with the 4.0 release. There was palpable demand for the offering. The moment anyone of them advertised that the new KDE 4.0 release was going to be on offer, all of them had to do the same. If I remember correctly, the developers had to make an effort to tone down the enthusiasm.
All in all, the only thing it has convinced me of is that releases are the spawn of the devil.
