I was a subscriber for 4 years and I can confirm that the Economist is crap. It looks good compared to other choices like 'Times' or 'Newsweek' which are totally unreadable.
* It has totally absurd double-standards: Russia, Iran, China and their puppets (e.g. Syria and so forth) are 'bad' and 'evil'. US, EU and the UK stand for 'justice and peace in the world'. If your world-view is so naive, then you deserve the economist.
* You never know the author. You never know the actual author's background so reading between the lines is (in the beginning at least) hard
* It has it's own view of economics, which most of the times is miles apart from the academia: If I had to choose between 'Buttonwood'[1] and Paul Krugman, I'd go with Krugman any day of the week. Having different opinion is one thing, diverting from mainstream academia views CONSTANTLY on 101 macro-economics is another.
* The Economist is extremely PRO-WAR. There is NOT ONE instance that I recall the economist NOT backing a war: Afghanistan, Iraq... Latest one was Syria. The magazine's editor, openly called for the USA to attack Syria. The article (main article btw) was awful and brutal.
Are there any good articles in there? Of course. There are many good articles featuring in the Economist. But overall it's not nearly as good and fair as most people think it is.
I don't know if the editor changed after 2004, but me and many other readers have the feeling that after 2004-5 the quality dropped incrementally.
Generally speaking I found "The New Yorker" to be the best[2] magazine so far. I think part of the reason is that it's not on the spotlight so much, as the 'Economist' and the authors receive less pressure to push a specific agenda.

[2] When I say 'best' in this context I mean avoiding 'double standards' giving everyone a voice and so on. For example check out the articles on Wikileaks, Assange, Snowden or any controversial figure in the Economist vs New Yorker. The New Yorker features interviews, articles and views from both parties, not only from the US gov. The Economist on the other hand even when it tries to be fair to someone, uses diminutive terms like "unorthodox", "unconventional", "self-proclaimed", etc. That's not journalism, that's manipulation. The worst form of manipulation.
