I'm working on a venture that combines straight forward forum functionality with Facebook like real time community discussions. The Facebook-a-like part uses news items to drive entries and encourages the community to comment on them.
So here is the question - would you advise:
a custom coded solution / adapting an open source application (if so can you name one) / going with a proprietary solution (if so can you name it).
For those who respond - I'd be grateful if you could you provide some basis for the opinions expressed.
