I regret the situation led to the OP feel discourage about the NLP community, wo which I belong, and I just want to say "we're not all like that", even though it is a trend and we're close to peak hype (slightly past even?). The complaint about pollution of the Web with artificial content is timely, and it's not even the first time due to spam farms intended to game PageRank, among other nonsense. This may just mean…
Every content system seems to get polluted by noise once it hits mainstream usage: IRC, Usenet, reddit, Facebook, geocities, Yahoo, webrings, etc. Once-small curated selections eventually grow big enough to become victims of their own successes and taken over by spam.
It's always an arms race of quality vs quantity, and eventually the curators can't keep up with the sheer volume anymore.
