I’ve been told:
Apparently http://www.mashada.com/ used to be a kind of central meeting
space for them , but the coordinators started getting overwhelmed with
hate messages so as you can see closed it for a while, and have now
started this.. http://www.ihavenotribe.com/ instead.
And meanwhile they’ve also set up this.. www.ushahidi.com which seems to
be the source for a bunch of other more mainstream info distribution.
