Most posters (not necessarily members) come here for ND football news and talk. After that, I'd say the top reason for posters coming here and taking the time to read and type words on their screen and submit them in a thread is because it's their escape from their wives, girlfriends, kids, job, mortgage, bank account, health problems, societal and world problems, etc.
In other words, it's kind of why many men have Poker Night, have weekend trips to Vegas, or join the KC, Masons, Elk Club, etc. It's a safe oasis for like-minded people joined by their love of ND football.
I'm kind of with GK here. While women and 14 year olds can add something of value to this site, I'm not exactly sure what it is. I guess the one exception I can think of is if we get another STL-- a kid that likes to share a lot of recruiting info on here. But then STL got older, and became one of the dudes.
