I have mixed feelings about ER. The photography, graphics, and layout are first-rate, although I've found a lot of the writing to be poorly edited for grammar and spelling (that's picky but I was an English major. Pity me).
Unfortunately the content leaves a lot to be desired - one can usually read an issue cover-to-cover in an hour or so. And I've found a lot of articles lifted directly from the internet. It's not been every single issue, but it's often enough to get my attention. It's a very well-put-together mag but why pay six bucks an issue when I've already seen half of it for free?
They have a real chicken-and-egg problem. Personally, I'm not going to subscribe unless the content improves, but how can it improve if no one is buying?
