How to network all the friends of community libraries of Africa?!

At FAVL we're working on creating a Google Earth database that will be linked to wikiable pages where library friends can upload information, photos and comments about libraries that they support and visit. But why re-invent the wheel? Some library supporters have already started using the TakingITglobal portal for just such a purpose. It is a great example of what we have in mind. So now the hard question... follow Sara Switzer's lead or carry on with our own possibly clunky efforts?
