This is awesome and much needed.
Just throwing it out there, but would you consider making a dump of the data you scraped that could be used by data scientists? Maybe as a torrent or something like that? Data about movies and what people say about them could form the basis of a lot of NLP projects.
What other big datasets are there for forum post text data? The reddit dataset most immediately comes to mind, and I've also seen a similar one for HN comments. Any others?
