@pandora_parrot @joelle Yeah, it's weird. All the big services were a long-distance call when I was a kid, so I never really got into them. I got my start in computer-mediated-socializing on dial-up BBSes run by individuals literally out of bedrooms.
Some sysops were adults, some were kids at school. Almost anyone could start one up as long as they could afford the computer & phone line. Not an insignificant barrier, but not entirely inaccessible.
When I eventually got on the Internet proper, folks were doing much the same thing with usenet and little web sites on university servers and eventually blogs. My first job out of college was at one of those tiny regional ISPs. It's been really grumpy-making to see all that consolidate back into a few silos.
