A good place to join the intellectual debate, and from which to refer new visitors to STR, is The Guardian.
It began as an English newspaper early in the 19th Century and was a backer of the "Manchester School" of the free-market liberals. After the latter turned coat to statism around 1909 the journal followed, so today it has a left-of-center political bias. But its open forum, called "Comment Is Free" or CIF, is very well designed and run. The managers are actively courting US-based contributors, so there's a refreshing international flavor.
Additionally it was a Guardian reporter, Glen Greenwald, who broke the Ed Snowden story.
Opportunity knocks.
