while I agree that like many I don't see the point in having wikipedia read to me, in their favor they do have pretty design. This looks more like a visual communications senior year project than a company, but maybe they have something else up their sleeve.
Then again I thought the same about dropbox, its just rsync, some server managed storage and a webapp on top. But they seem to be well liked. It's hard to predict what will stick and what won't.
