This is from a talk by Benjamin Mako Hill during the all staff.
When people land on the wiki main page, they are usually being shown a "view source" which would mean to them that they can not edit the wiki. A possible feature would be to replace the text by "edit" and send the user to a sandboxing page. This way, they will know they can edit the wiki :-]
