Neocities[1] and tilde servers like tilde.town[2] is a pretty large hub of old-internet sites. It's a free Geocities-like host that's home to a lot of neat, creative sites.
You can also get a VPS for about $5/mo and have your own self-hosted server with whatever servers and web apps you want, like an RSS reader, an IRC client, FTP/Gopher server, etc. (Shameless self plug: this is what I do with my own personal site, https://invisibleup.com)
