Personally, I prefer to “own” most of my SenseMaking, so I write my own WikiLog (and PrivateWiki), and read/link elsewhere without a forking style. http://webseitz.fluxent.com/wiki/WikiLog
And when I join a team (typically in a business) to actually get something done, I put in a single shared TeamWiki to attempt a high level of convergence/coherence of a SharedLanguage. http://webseitz.fluxent.com/wiki/SharedLanguage
SFW is spelunking in some gap between those cases. http://webseitz.fluxent.com/wiki/GroupFormingNetworks
