I go to a VERY nerdy school, where I could find a group of people in any dorm, talking about magic, ygo, sc2, dota, lol. Most people ive talked to about mons have actually heard about vgc smogon showdown and the like but are just casual players and dont have much desire in being as hardcore into mons as how smogon/nb think about, think 1100-1300 elo. They don't tend to be aware of the metagame, hazards, etc. to think in terms of competitive mon battling, so I just end up randbatting them whenever we decide to play.
Ive happened to meet some peope irl via smogon and one case of knowing the person irl already and finding out they go on smogon, but with just one exception, I have not actively talked/hung out with these people mostly because we tend to have lives independent of each other and that's been more of a priority. If our paths happen to cross, I'm down to grab lunch or something, but it's more likely that life happens.
