Personally I do. Maybe even 4 hours a day. What's worse I don't even like the "discussions" if you can even call them that. Mostly they are repetitive echo chambers of particular community/moderation. Hopefully nobody was offended.
I do evaluate "Why am I here?" Part of the I moved into discussion forums was due to being afraid to face the world out there. Thinking about having a kid increasingly steers my mind to letting go of the forum.
For myself it's the relationships I've made. I don't really bother much with the forum itself although it's great ... got banned for 6 days and it felt like an eternity to get back to my mates
