It doesn't make sense for people to have joined this site or GAF initially for a reason other than video games. I understand people who joined GAF way back when for video games and since then have stopped playing but still like the community, that makes sense. But if you claim you joined initially for reasons other than video games, that seems strange.
It's not even close to being strange.
Person views forum. Views gaming. Views OT.
Likes OT, signs up because of it.
What is even remotely strange about that?
