Is there a live chat ?
You mean like live support?Or live chat between 2 users?
I'm guessing a live chat between 2 users. I guess there can be some simple chat but I don't see the reason for it. All the communication could be done in comments or in private messages.
This is the better interactivity, everyone can show their talent on it, to share their new, we can give the creators of our own like some reward, this is a very necessary developing direction
