i usually find a topic that interests me and start looking for very specific info about it and archives, ie i spent a whole day digging thru myspace profiles on the wayback machine to find event flyers from that time
the old-fashioned way, like you would before the entire internet was monopolised into basically three conglomerates. why would you spend all your time on your computer swapping between instagram tiktok youtube pinterest when you could find some of the coolest websites you've never heard about learning information your algorithm would never feed to you!!!!
a good place to start is your favourite artist's websites (not just musicians!) sometimes they have blogs (especially if they're writers) and often they link websites they like.
I also like magazine websites - the face, angel food, hot literati
or craigslist missed connections. I check the new york section all the time
