I join maybe .01% of the forums I visit nowadays and that's purely for access to something I cannot attain elsewhere. Five years ago, it was a different story. Today, I own a few sites, admin and/or work on others and just don't have the time for most forums. It's even difficult to find time for my own (personal) sites, including one site I've been threatening to start up for over a year now. If time wasn't an issue... I'd spend more of it where it counts the most.
