Andre-
Perhaps. I'd say it's worth the try. And I don't think that waiting until we have all that will make the enthousiasm any larger. At least when we put it up, _something_ will be made.
Something will be made, yes, but that something may be difficult to build upon - in terms of content, functionality, structure, policies - and grow into something tremendously more useful. That is the crux of my argument.
If you can convince the others (vote, consensus etc.) that we should set up a blank wiki now and add all the other functionality later, regardless of all the problems that may ensue, then I will follow along, but my position remains that we should properly plan and develop a basic set of features before publicly launching this project with great fanfare, to make sure that we have a solid foundation to build on, and that we get the greatest possible interest in the important early stage of content development.
Regards,
Erik
