I'm the opposite of this. I spent most of my life up to my mid-20s on internet communities -- first Usenet as a child (8 years old), then SA, then Reddit/4chan. I mostly read Reddit and HN now, but do not read and post compulsively like I did previously. I would easily clear 200+ posts a day on SA and 4chan. There's also the different pockets of people that I met through gaming.

It's been hard, but I've finally broken away from relying on the internet for friends and community. 2017 was the first year that I can remember where I spent more time with RL friends than internet friends.
