Right now, it's manual. We're itching for machine learned solutions...perhaps the first step is to do it manually and use that labelled data later. But you're right, it's a huge challenge, and we're not sure how to do it.
thanks for your feedback!
monetization is pretty far out at this stage but it's definitely on the to do list. And yes, content is important, we spent a lot of effort aggregating and curating the events, and there's still a lot of room to improve on that front. Can you explain a little bit on what you mean by API for event creators? Thanks again!
