Where's the social networking stuff? All looks like regular sales-y IBM spiel to me.

This will fracture the community rather than bringing it together.

There are only so many sites folks have time to hang out on - of course z World would be moderated by IBM rather than being open to all as IBMMAIN is....

IBMMAIN? You mean this mailing-list thing? http://www.nnseek.com/e/bit.listserv.ibmmain/

That's not really anything like MySpace is it? It's a bit short-sighted to point at these new social networking sites like MySpace and Facebook and say "pah, email lists are already doing this".

That said, the "Destination Z" lot don't seem to have got the idea either... it's just another sales-pitch site. So, I wouldn't worry - you can go back to your emails now :-)
