Works well if you're communicating while you're making changes in code. At my work 20 people are changing the same wiki-page when we do heavy regression tests.

Works well if you're communicating while you're making changes in code. At my work 20 people are changing the same wiki-page when we do heavy regression tests. Works like a charm (not everyone is writing at the same place in the document since we are testing different things and writing results at different sections).
