As a completely anecdotal data point, I read a bunch of tech news sites (preddit, newsyc, engadget, etc), but I had never actually clicked through to read anything about Powerset, and had no idea that they'd been working for a year or two.
It's (just about?) an impossible task to get anyone to switch from Google, so the _only_ chance they have is to imply that they are in fact different, much better, and yes, Google-killers. So, while I agree with the article in that the results aren't there yet, the only way they're going to get any traction is if they're simultaneously making the product better and screaming very loudly that they're awesome.
So, while they may have under-delivered, I don't think they've over-promised, because I still haven't heard any message, and still don't care much. I'd be more than happy to give'em another 30 seconds in 6 months to see if it's better than "key words wikipedia".
