I completely agree with you. I've been a subscriber for over 12 years, so maybe similarly biased. A good test case for me is whenever there's an article about something I have in-depth knowledge about it's rare to find grievous errors. A reverse Gell-Mann amnesia if you will.

The articles that are posted here are usually from the Leaders section, which are in effect opinion pieces. For every Leader article there's also a more in-depth article. If your only experience with the Economist is through their Leaders I can see how you would come away with the idea that all their articles are biased and lack detail.
