I seen that too. It has become especially apparent on a small sub I still view as it didn't really migrate.

It went from people in their 20s discussing shared experiences with a medical condition, with the occasional high schooler dropping by to ask something. To babys first experiences, with condition. Absolutely filled to the brim with 13-17 year olds.

I'm fine with them being there and asking questions and talking, but not when every post and comment is just more teenage drama.

I seen a similar thing on another sub, while that has always screwed younger then the first, it definitely feels like it dropped like 5 years in average age.
