I'll see your opinion and raise you an anecdote. At our business we use Confluence. The earlier versions had a proprietary wiki syntax that us technical types found easy to use but the rest of the company did not. Confluence added a visual editor and since then the quality of the non-technical documentation in Confluence has improved, because the ability to edit it is more accessible to the people that know the most about it.
