Are there other sites/social media that also do this? Every decentralized social media I've found so far has practically no user base. This is the first place I've seen that actually has users and good content.
There is ZapRead, but that would be an example of your "practically no user base" complaint. Their UX is just not conducive to what I like about SN, as I want: "quick, show me things that might be interesting".
There is also y'alls, which is an LN clone of the now-defunct Yours.org (which was created by a BCasher who then became a BSVer).
There is Value for value (V4V), where listeners can stream to podcasters. Some podcast players, such as Fountain podcast app, have this.
Substack announced they would be letting newsletter writers to be paid in bitcoin. (Sigle, which shitcoin-related, is similar).
Brave Rewards could have been great -- where you tip to "verified creators" right from the browser. But they started out with a shitcoin token premise (rather than LN) and withdrawals of (currently measly) earnings are to KYC exchanges only.
There's a smattering of other content with crypto rewards, Cent, Hive/Steem, Publish0x, DLive, Bittube, Lbry, and more exist... are shitcoin based, and are probably also all in the "no user base" category.
