If clutter made it harder to form a mental model then everyone in Vegas would be lost.

edit: But the reason everyone isn't lost is because Vegas is basically one straight road with flashing lights on the sides. Which is more or less what I'm proposing.

Also, I see your point about the knowledge seeking demographic. Not sure whether I agree or not. For every Jimbo Wales looking to hire a philosophy postdoc, there could be a hundred MySpacers looking to hire someone to clean out their bongs. Or maybe not, who knows.

Also, on a different topic, there should be a way to embed ads for experts onto my blog or homepage.
