I don't think so. Part of me hopes to be here in 2019 so that I can include a 'best of 2010s' segment in my year-end countdowns, but part of me thinks I'll stop posting years before then. Perhaps I'll stop regularly posting, but still come back at the end of each year for Best of. At any rate, I doubt I'll still be here at 30. That's midway into the 2020s for me.
Maybe. Probably not as much as now, but posting in forums is an easy way to communicate about stuff you can't/don't want to talk about with people in your environment. Also it's a great place to spend when you're really bored
I don't visit other forums. I'm 19 and have been here for about two years. I'm finding it less and less entertaining, so I doubt I'll do this in 11 years.
