I’ve brought the list of other tildes as up-to-date as I can currently make it. I’ve removed tildes:
that have told me they shut down
whose URL no longer resolves
whose URL redirects to a domain park or other non-tilde project
I have started a list of defunct tildes so we will never forget the tildes that have fallen by the wayside. Right now I have just copied their old entries from the original list, but I hope to turn it into more of a memorial page with screenshots if they are available.
RIP defunct tildes.
