I have been a subscriber to Discover for years. I used to love it, but the lackluster articles and cookie-cutter format started to turn me off. The content never lived up to the cover.
When I found Science Illustrated, I found my new favorite magazine.
I just renewed by Science Illustrated subscription for another year after realizing how much use a single copy gets. I read it... sometimes scanning articles for safe-keeping. I love the photography (I'm a photographer myself). My wife reads it (she's no scientist). Then I bring it into the break room at work and it gets circulated around for at least a month afterwards.
With great illustrations...
