Has anyone done a heuristic or usability tests on a wiki?
I am working on a study now to identify areas for improvement.
I am using standard usability heuristics, with a few more points of my own choosing to add more to the web 2.0 aspect.
A few things that keep cropping up are:
Wikis have their own standards ("main page" instead of "home" and tabs for actions instead of links, I've no idea why), but these, I believe would be barriers to non-wiki users (the target user in my case is not necessarily familiar with collaborative websites).
Another problem is the generic "edit": sometimes there's too much distance between the target and the link, so here maybe it's best to use more explicit text even if it looks messier, e.g. "Edit page", "Edit title", "Edit description".
Also, some mix the language used, for example: "Page" (noun), "Discussion" (noun), "View history" (imperative), instead of all nouns or all imperatives e.g. "View page", "Discuss page", "View history" etc.
I'm also including ideas about motivation and engagement, the kind of thing Joshua Porter describes in his book on designing for long-term partipation, though this is more content-related.
Should anyone have any other "wiki heuristics" or thoughts, I'd be interested in hearing them.
