I am a LONG TIME KDE user and I like it, most of the time BUT if Seigo wants less complaint I have some suggestions:
1. Fix Bugs, in a timely way OR document workrounds
2. Stop the feature/menu/config churn and the ape M$ mentality
3. Write decent documentation, KDE's is the worst nonsense I have seen and an auto API extractor is NOT documentation. The documentation of configuration options is particularly BAD!
4. Emplace a build system that says (download [a] ... [f]), cd foo, make or some such and have this verify the correct version of prerequsites, libraries, .h files ...
If I have to read the code of Qt, Kxxx and external package yyy to isolate a bug you have failed.
The Seigo response to being Tovolds bashed is juvenile in the extreem, Linus has a sure sense of design eg Git, outside the Kernel, and a rational appreciation of what most users need is vital now that Gnome is well on the way to the junk yard at the hands of its developers.
What the community needs is Seigo to remove head from ass, and to ensure that the KDE development community is balanced currently it is "Übernahme durch germanischen Denken und Methodik mit einer unwarrented elitäre Haltung beeinflusst."
Do not misunderstand me please, KDE is good and improving all the time, but it could easily be made excellent and thus become the de-facto style leader on the Desktop as Android is in the mobile space.
