I'm 48 and working on shifting back into coding after too much time doing more generalized IT consulting/support/admin/etc. for medical practices, and I'm not nearly as likely to spend time on Stack Overflow as I was 6-7 years ago.

There's still useful stuff on there and some gems, but it feels like there's a lot more cruft to wade through as well and I'm not feeling the same desire to surf the site or look for questions to answer because that's just not as personally rewarding as it once was.
