These guys are doing some sort of NLP magic and it seems to work really well. If they could get reddit in the content stream, that would really encompass all the content I'm consuming
If anyone has ideas for other content streams, including their own, you can email us and we may open up an endpoint that analyzes any text and returns its category along with unambiguous topics.
In general, we're excited to see what developers can do with our API. To try it out, be sure to check out our api demo:
By the way, some more details: we have semantic search. Try something like "indie rock" and it'll return posts about indie artists. You can also try music genres, movie genres, cuisines, and more.
