Yeah, I send out memes (a lot of screenshots from twitter and tumblr, honestly) and content from imgur/reddit. I curate the content and send it to people who are interested in that kind of thing. It's obvs not for everyone but I have subscribers that seem to enjoy it :)

I also sometimes send out essays about things I've been thinking about. My last email had about 1k words about millennials (I am one, ftr) and what the media was saying about my generation.

It's not for everyone but that's something I enjoy about the email newsletter medium - you can always unsubscribe.
