WhichWikiShouldWeUse

The other day, on a page I cannot find now, someone suggested that we might switch to a version of Wiki which supports arbitrary linking. The idea is that, particularly for an encyclopedia, having arbitrary links is better than the amusing but odd wiki capitalization conventions.

It strikes me that a very simple system would be to be able

to link like this: <<< United States >>>.

Is there a wiki software that can support this?
