I found these guys because they blogged about Thinkcycleand saw what i saw: no activity for a while. But life goes on.
These guys are interested in tools to help build online communities and to engender interoperability...so that each community isn't a little island - but states with maybe, i dunno, roads between them? Maybe sites want to keep their people where they are, but i think it's like having a PDF format - it helps everyone if you can read everyone's work.
