Thanks! This place isn't meant to discuss my personal experience of course, but nevertheless thanks for your remarks. Perhaps it can serve as an example why contributors get disappointed in Wikipedias. It's not that I don't see the reason to contribute anymore, I still see them and will of course return. It's not that I crave attention (en:Wikipedia:DIVA) or want to see people supporting me in the particular topic at hand. It's the simple fact it's no longer a nice hobby. When that personal border is crossed it's just time to take a break.
Everything you mention is true. I'm usually the patient type in discussions, trying just to say what counts and ignore it when others don't read/get it. Yet, if we really want to be able to raise quality to a higher level than the ruder part of our contributors is able to understand, we have to somehow get over the barrier of discussions being decided by ignorance and self-over-estimation.
