It depends on what you mean by a "chatbot platform".

If it's a way of developing a single "chatbot" and having it work across multiple "platforms" (think slack, hipchat, irc, facebook, standalone, etc... maybe even including voice-specific platforms like Amazon echo and Google Home). I would LOVE that. However it's going to most likely suffer from the same issues as other "platform-independent systems" which is that you'll be developing to the lowest common denominator.

If it's just a way to make a chatbot via a GUI, I'm personally not interested at all.
