Yeah it is best if you already have some kind of community then build your forums from that. Things that could build a community could be you being active in discussion in other social networks like on your Facebook page, Twitter, and Youtube channel. You could also easily build your forums if you have active commentators on your WordPress blog.

There is also a plugin that could just replace the WordPress commment form with bbPress topics, so if you are an active blogger this will help drive your community to the forums.
