Be careful: a lot of purveyors of "economics knowledge" on the web are trying to sell you an ideology along with it.

This is fairly neutral: http://www.introecon.com/

A good author is Tim Harford, who has some "popularized" economics books that are, once again, reasonably neutral.

In particular "The Undercover Economist" and "The Logic of Life".
