Though I sometimes struggle to keep up with them :)

Edit: Also not really a newsletter, but I enjoy getting the Medium Weekly Digest

If you're dedicated enough, you can run OS X on a non-Apple computer too ;)

Currently Macbook Pro running OS X.

"minimalistic" is not a word, and that isn't minimalist design.

Recently moved to Anchor from WordPress. What made me choose it was that it's lightweight, fast, and runs on my existing PHP/SQL stack. I'd say it's still early days but it's very a promising project.
