Huh, that seems different from what I'd have expected - but then again, I'm not sure of what I would have expected. Thanks.
I've just fixed a bug in my scraper that was causing it to abandon 25% of the corpus. This has ended up tripling your contribution. Some new values for you:
agi -> 37.328
intelligence -> 22.367
moral -> 21.010
agis -> 20.087
eea -> 18.647
takeoff -> 17.500
credences -> 17.108
machine -> 16.902
our -> 16.222
environments -> 15.919
deer -> 15.761
This retains a similar "flavour" to the previous set, (AGI and ev-psych). The best way I've found to interpret it is "what sort of words describe what I use Less Wrong to talk about?"
As an interesting side-note, rot13 really messes with TF-IDF.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
