...start your forum? I'm guessing most of us will say personal passion, but there are probably those who started them in profitable niches, because they were P.O.'d at other forums they participated in on the same subject, or oh, I don't know...on a dare? I started ours because I wanted more information on a subject and couldn't find it on the net. I saw a vacant niche and took it, and pulled some peeps from another forum that was less than focused on my subject but which was nonetheless getting most of the traffic. You?
