lol @ my, erm, heterogeneous list of contributions – Ukrainian riot police and basketball uniforms! :)
Watching these made me think about one thing we should probably start to pay more attention to: the network of
usertesting.com users we've built up over the years. I've definitely seen two of these folks (misterbeauds and kayaker) before in usertesting tests I've run, which means they've had an unusual amount of exposure to the details of Wikipedia UI, both current and planned. That probably partly explains why they seem to know about things like page history, watchlist, etc., without being "real" editors.
Every time I put a test up on
usertesting.com, I get at least one of those repeat testers – probably because our Wikipedia tests are a lot more fun than whatever standard eyeball monetization software these people normally have to endure ;) But that means we might be underestimating their level of expertise (since they're not truly naive users) and over-representing their views of our UI improvements (since they tend to offer up similar soundbites time after time – e.g., kayaker's "this looks like code" and "I don't want to mess anything up," which I've heard her say before).
Anyway, just something for our future Lead UX Researcher to tackle, probably with a detailed database/registry of past testers :)
