I read the Washington Post's education section. I have no problems with the 10 article limit because if I look at the titles, most of the same stories can be found on other sites for free. Jay Mathews' articles are not behind a paywall if anyone cares.
I don't understand how some of you think that a newspaper, or any site, can stay in business providing free content especially if you are using ad block. Take your non-paying business elsewhere.
