Hype is a bunch of people claiming something is good. If there are enough people, you should probably go find out whether it really is good. If it really is, then voila! Progress happened. If it's not, you stop. This guy is busy finding out, that's all.
Fair enough, but I fear that most of the time hype comes from people who fear missing the latest boat, or who think it'll help them if they say stuff like XX is cool (a misplaced positive attitude always helps more, than misplaced criticism)
With mass globalization of the hype, we have countless examples of hype - even for programming - around things that aren't especially good.
