I miss the days of people actually creating their own website/homepage. Just using QB as an example, there were so many random sites that had maybe a handful of programs someone wrote that aren't hosted anywhere else that have now been lost to the sands of time. We have archive.org but most of the time the downloads don't work on there (even more so for stuff pre-2000). It's pretty cool that Lycos is keeping the old Angelfire and Tripod pages alive so the sites still work, or at least as well as they did before being abandoned.
I don't think it was Neocities doing that. Neocities came in to fill the gap that Geocities left but a few years later. People don't seem to be interested in making their own little places on the web as much anymore so while there's some cool stuff hosted on Neocities, it's still tiny compared to free simple hosts of the past.
https://geocities.ws/ was one that I remember that was archiving all of Geocities (aside from archive.org). I don't think they got NE or not all of it at least. A lot of archives just have my 'Website Down' version of the NE Geocities site due to most archives being from ~2007 or so. Also, I had a bunch of sub websites in sub directories that never made it to any archives. There's I think a blip of my Resident Evil Total Conversion for Duke Nukem 3d, my old skateboarding website, and pieces of the Wry & Doomed Qbasic projects pages on archive.org. I also had a video game review website that actually had a good amount of reviews that's gone (I used to post them to gamefaqs.com before making my own site) and old band websites that are also gone. I really should have just downloaded a copy of my Geocities account before it closed. I knew it was coming and didn't do it for some reason.
Welp... started rambling again!
