First, it's an awesomely cool idea. Congrats to the Wolfram team for pulling it off so far.
Second, it's a freaking huge project. As much as they have, I can't help but think they're only about a 100th of the way towards something that might be truly comprehensive. Maybe a 1000th of the way.
Still -- kudos for setting it up. I sincerely hope it grows and becomes all that it can be. It will definitely take web research to a new level.
