I think something does exist in Ethereum platform but why it doesn’t exist out there anywhere else.
Svbtle is also good if you don’t mind mandatory Google Analytics that you can’t disable (I left the platform because of that).

The internet has changed a lot in the last ten years. People have realized that popular content has a big monetary potential, and it is far easier now to get compensated (remember when YouTube content creators couldn't monetize?). More content is created as a income source, than out of passion or interest. Search results are gamed by commerical blogs. The average hobby blogger can't compete with that.
LiveJournal went closed source in 2014. It was also bought by Russians, relocated its servers to Russia, and began enforcing Russian law in 2017, which included laws against "gay propaganda", which was when me and my remaining friends abandoned the service for good.
