“Garry Tan and Brett Gibson were two of the co-founders of Posterous in 2008. Posterous was acquired by Twitter in 2012, and while we were happy that it was a meaningful acquisition for the team and investors, we were bummed to see something gets shuttered that we believed should last forever.”

Posthaven is pretty minimalist and still there.

PS. As many comments here are about fonts, the most recent (rare changes, as in, back in 2016, which is a "good thing") feature update to Posthaven was customizable html/css: https://blog.posthaven.com. Also does post by email, custom domains, and rss feeds.
