He started Bomis webrings too, but Bomis was not all bad in part because it financed the start of Wikipedia.

Brad,
An area I know nothing about. The site seems very new.  Are you close to it?

I assume there is an app, but I cannot see one. Looked for reviews, and I can find nothing.

Can you fill in any more?

Rupert,

I know nothing about it and I have not joined.  I did see a post on another social network by someone who joined, they are asking for a voluntary subscription fee to pay the overhead and keep it ad free.  US $12.99 suggested.

I don't even know the layout ie. Twitter like or FB like.   It could just be a Mastodon retread.

Sorry, all of that is not much help.
