There's revivals of a few of the services here. Off the top of my head, myspace has spacehey which is moderately popular. AIM and MSN messengers have revivals out there but I forget the details. Neocities certainly isn't geocities but it has a similar vibe and name. They mention winamps resurrections, and at least in the unix world we have a few players compatible with the skins (which lets be honest here, why else would you want to use winamp today). Pebble came back recently. Dial up exists as well, but is mostly relegated to the extremely rural and will probably die out when satelite internet like starlink gets more popular. And of course, homepages never died for anyone moderately interested in computers

Minidisk is technically dead, but it still occasionally gets new releases, particularly from the vaporwave/y2k scene and needlejuice (they have Lemon Demon and the Friday night Funkin' soundtrack)
