I had heard of Lemmy before the Reddit API debacle, same as I'd heard of Mastadon before the Twitter Elon debacle. Just as the Twitter debacle really pushed me toward using my existing Mastadon account, the Reddit debacle is pushed me toward actually finding a Lemmy server to join and signing up.
I'm 57 (58 next month), so I was in my mid-20s when the Internet of the 90s really started to form. What was crazy was being in college and wandering over to labs on campus that had access to the latest protocol, https, and seeing Mosaic for the first time and kind of fantasizing about that being the future of the internet. ...and it was. But not always for the better or for the benefit of people. By the time I moved to San Francisco (not for dot com myself, but my spouse was in grad school) in 1999 the dot com boom was in full peak force about the crest the edge of the wave and completely bust in a couple of years (and hoo boy did it). The commercialization of the internet was utterly and completely underway during that early 2000s period, but I was still sort of shuffling around telnet based BBSes and still pulling a lot of my files with FTP. GOPHER was long gone by then, though, and usenet was always more of a hardcore user area in my personal circles (mainly due to the the fact of how overwhelming and disorganized it could be to me, which is so incredibly laughable now).
The promise of those early telnet and early web days almost completely disappeared and a lot of those people who saw the internet as a democratizing force either did find a way to make money from it or they just found jobs and turned into Makers during the 2000s. Now it feels like a lot of those Maker folks have started to find ways to come back to the internet in ways that bypass commercialization in order to have methods of having communities that aren't targets for bigots and fascists to intrude on safe spaces that a lot of people felt like they had found initially.
And it DEFINITELY feels like a lot of tech nerdy Millennials and Gen-Z have completely tired of the commercialized internet entirely and are inventing and finding ways to control their own communities. And friends... I fucking love it.
