For what it's worth, here was my reaction: At first I was thinking "cool". then I read that headline, and thought, "I hadn't thought of this as something I need to trust people with. In fact, now that I think about it, I bet that's really hard to pull off." Then I thought about the crazy non-contextual intellisense stuff out there and was wondering if the whole mess is even possible without turning the website into a spamfest.
