I think we should all calm down a bit.
LinuxMCE is an incredible project. The developers, though very stretched, do an excellent job and are much appreciated by those such as me who are not in a position to help with the development. Nevertheless it's not perfect, and there are clearly challenges in the pace of development and the accessibility of information. Setting up LinuxMCE isn't easy. Developing for it is clearly a nightmare. At the same time the more people who are encouraged to try it and find their own needs, the more it will be tested, and expanded.
We should all try to encourage each other, and move forward. There isn't enough spare effort going around to waste it on arguments, particularly if it discourages people from getting involved.
