In the past, Posterous was a blogging service that was powered by email, and I loved it. (You could blog using the email body and attached photos were also posted, so Daft Social without the "minimalist" part.)

Sadly, it was acquired by Twitter and then shut down.

I like that relying on the standard email protocols means you don't need an extra client to post. I wish more services could be powered by email - it is already so old, yet still underestiated as a protocol.

PS 1: Now someone just needs to give me back my BlackBerry...

PS 2: It's great they also support another standard, RSS. Two features that I would like to see are: (a) subscribe to these RSS feeds as email (for symmetry, so I can read all in my email client if I want to) and (b) two-way interoperability with Mastodon.

PS 3: I can see others have pointed out their liking of Posterious below already, so this feature should have a future in some form or another!
