Sure, wikis have tools to allow people to change others comments and review a history of changes, but I'm yet to see a wiki editor with "Track Changes" similar to Word or Open Office and consequently we don't edit wikis as much as we should. In particular, we don't remove irrelevant content, an essential component for clear, concise articles.
The problem is that wikis don't help us honour the unwritten social law of reviewing.
"It is OK to suggest changes to an author but it is disrespectful to change content without the author's blessing."
The writing workflow should be:
- Author writes
- Reviewer suggests changes
- Author accepts or rejects changes
- Author 1 writes, and asks others to extend their page.
- Authors 2, 3, 4 add content (making sure not to remove prior content). Wiki is published after each update.
- Time elapses
- Author 5 wants to clean up the page
- If dedicated, author 5 looks for all previous authors to ask permission to consolidate their text.
- Author 5 rewrites the page.
