At the beginning of a project it's easy to fantasize about how it could grow in a million different directions and really take over the world. As you develop it, the scope constricts until you have a well-defined thing. I think the Rocketr guys are still in the early phase, before what it is they're doing has really collapsed into one realized thing. That they don't have anything online you can actually see, combined with their overly expansive description suggests this. The hate is excessive, but as hacker types, we're sensitive to excess verbiage without much to see. We distrust programmers that talk the talk but can't do FizzBuzz, and we distrust companies that tell us their product is amazing without letting us use it or at least see some screenshots and maybe a screencast. Steve8918 below really hits the nail on the head: we don't need more better words now, we need to see something. I think PG was probably right not to invest now. But maybe in a year, they'll have figured out what it is they're building, and maybe it will be fantastic.
