I think what's compelling is that there is some sort of critical mass on the API side. We've tipped in the last year or two over to many (if not most) Internet things being accessible by API. It doesn't seem surprising to me that companies are re-looking at matching up typing and text with these APIs, and coming up with some interesting use cases, especially with better NLP here in the last year. I'm not doing anything bot related, but I think it's a (reasonably) exciting space right now.
