Guest, you make several really good points. I didn't intend at all to "single out" OpenSim. My purpose in posting is because OpenSim actually has a rep for infighting... not only users but its coders and designers. I see such regularly and... since OpenSim is free and should have avid and loyal support, I kinda wonder why people always seem to be arguing.
There is the occasional upset user on Inworldz, and of course the occasional drama queen and disgruntled user / enemy. Like you say, that happens everywhere. But by and large the Inworldz forums are very friendly, open and supportive of the grid. I'll agree that Linden Lab forums often seem like troll/flamer boards (or at least they used to. I don't much pay attention to them any more).
I was just making an (apparently lame) attempt at getting OS people to stop the petty bickering and trolling. From where I'm standing, it doesn't seem to be doing the project much good.
