so, would you mind showing any non-FANG, but write heavy site? Besides that, even the operation of most social networks should be very easy to be split into town-sized instances with batch-updates in-between instances (see mastodon specs https://github.com/tootsuite/documentation/blob/master/Runni...). What actually costs a lot is constantly surveilling all user interactions, data-warehousing that and playing out ads. None of which is necessary, and a 20ct/per user/per month should cover the actual service nicely...
