1) I'm not sure what search engine your using but that nevers appear to be the case for me.
2) If you ask for help about old Amiga's on a lot of the Amiga sites they don't seem to give a shit from my experience.
3) I don't know what you're on about but the Amiga are only more alive when it come to being more new computers, that because Apple doesn't allow clones anymore becauses some the companies making clones, pissed them off!
4) I don't know why Atari.org is so quiet a lot of the time but with a lot of the others have it's ups and downs and the moment a lot of the sites are quiet at the moment but give it some time.
