I look at it this way: when the sport acquires casual fans through sensationalism, hopefully a percentage of them will take the time to understand and inform themselves further about it, and pass that knowledge on to others who might be interested. When I was watching the 1st season of TUF and asked my TKD teacher, who is also an accomplished boxing coach and grappler, to tell me about full contact fighting and MMA, it sparked an interest which has endured. I never stop learning and this forum (and watching fights on YouTube or dailymotion, etc.) has been a huge help, as it may be to other (former) casual fans.
