Facebook and YT for various stuff. YT subscriptions include Scott Manley (mostly for his Kerbal Space Program stuff), Hickock45, 22Plinkster, and YankeeMarshal, and a long list of aviation sources that are intermittent releasing stuff at best.
Aviation podcasts and vidcasts.
Alway seem to end up poking around Amazon looking at things for projects.
Other forums are all over the place in topics, a couple for RV owners (thanks to
@gkainz for one of them), firearms, wood burning stoves, and both ham and commercial two-way radio, and cellular tech.
Slashdot (gone downhill a lot, but been there long enough that I had a five digit user ID before they decided to do away with those and hide them - place isn't nearly as good as long ago), Reddit, The Register (mostly for BOFH, but who can't love a website that's motto is "biting the hand that feeds IT?"), GunBroker, occasionally various Dodge Cummins diesel websites or forums, weather and weather station/monitoring forums and sites, and who knows what else.
Stuff I've drifted off off... Was a huge C|Net fan back when they were good.
Also TechTV led to following Leo Laporte to his own stuff and co-host's stuff, but I've gotten over it. His guests and cohorts cowtow too much to him anymore for my taste. Places like Digg went to crap. Fun in the early days. Mostly useless today.
Various electronics forums, used to be heavily into the MicroChip PIC series of stuff but nowadays single board computers with a bejillion inputs and outputs already available on multipin headers like the RaspPi make the need to gen up my own boards with a PIC, nearly obsolete.
Dunno what else. Quite a bit but nothing consistently enough to mention I guess.
