it's so obvious

This is probably too obvious to even mention, but why are craigslist and google the hot ones? Well, with google the strength of their search is a whole nother matter for people who understand complicated algorithms to talk about,

but as a humble user with a fine appreciation for the obvious, well... The design is eerily simple, no?

It's a white page. With a list of blue links.

Any idiot could use it...and therein lies a whole nother set of problems. (That's where my job gets harder. But Google Scholar is a nice touch.)
