The website is pretty light-weight/lean and "progressive", but is there a practical purpose that the community posts are one giant linear post history? That's about as useful as a tweet except there isn't even trending?
Well anyway, glad to be here, I'm looking through the lectures now and this is all very interesting! I think Quantopian has a lot to offer and is a great resource and a great expression for mathematical aptitude. A functional forum might improve that ability to make discussions and share ideas.
