I hang out on various entrepreneurial Reddit subreddits, both to get an idea for what people are building, problems they are having, and occasionally post about my own pain; and also to promote my own product. Every now and then I'll lurk in subreddits that are just stuff I'm interested in too.
I've also gone back to X/Twitter quite heavily (but trying to limit usage and avoid posting in anything politics related). It's hard not to get sucked into it.
Then occasionally sites like the Guardian for general news.
