Check out the trending posts in the #steemit tag, there's loads of stuff. I think that my thoughts in this article are echoing a lot of peoples' thoughts and others have posted as much.
The thing about facebook is that it connects to your 'real' identity, most of the time, and I think most people here aren't about that life. But it might be worthwhile to create a chat channel on rocket.chat, but I feel like it will become another place to spam links... I like the idea of smaller groups of likeminded individuals coming from the same place getting together and getting to know each other. If you find me on the chat, I am using the same username.
