Forums, yea or nay?

I have gotten some requests recently to add forums to the site.  I have been reluctant to add them because I think there are already many forums out there and am not sure how much value it would add to the Road Trip Ryan community. If you think they would be useful, however, please voice your opinions, thoughts, etc. on the demo forum:

https://forum.roadtripryan.com

I will be most interested in what sub-forums people think would be useful and if people would be willing to help moderate.
