I am about creating a world class discussion forum which will come with many features like facebook, twitter, google+ integration. Support for different language etc. My plan is to use SMF or vbulletin.

I'm also a web developer/software programmer but I don't frequent this thread due to my busy time doing things on the system.

Now, what I need is motivation, ideas on how to make it a world class that will attract diverse of people.

PS: I have a means of bringing in traffic, more than 10 pro means of driving traffic but I'm still working on both the SMF and vbulletin on my local machine before going online.

So I'd like ideas from pro here and also to meet pro and discuss ideas here. I'm open to ideas.

Thanks.
