As the creator, Paul Ford (also), defines it, "a cool place where people can just hang out and make web pages on the web".
The Tilde Club no longer accepts new members, which is unfortunate but understandable since this is not supposed to be Ello but rather something like an doomed-utopian Geocities, webrings included. And I do think there’s something wonderful about randomly clicking through the webpages Tilde members have been “making on the web” (eg. this page that pulls you beyond the 1990s cyberspace event horizon). As Ford tweeted, it’s refreshing to see people doing things rather than just saying things — which, coming to think of it, would be the core difference between the Early Web and the Centralized & Appified Web of nowadays.
A triumph for the Indie Web!
