Amiga.org is good for classic Amiga users, for the next-generation Amigas and clones there is
AmigaWorld.net, and for the AmigaOS 4-specific zealots, there is
Amigans.net (although you will not find much history about Amiga on that site since it is fairly new), for the Amiga clones you'll find info about AROS at
AROS-Exec.org and MorphOS news at
MorphZone.org.
