Some of us lived through well over a decade of false promise, vaporware, company stupidity and out-right lies. As such many wouldn't piss on Amiga.com etc. if it were on fire.
Like wise we have seen others like UAE, Aros, Pagasos, Minimig, and others actually do some incredible stuff. But we don't agree which direction is best (just like the old days with PPC, Alpha, etc.)
Call it jaded. Enthusiasm sometimes comes off as idiotic. New projects are spurned as we don't want to get our hopes up. (natami)
