I will start on a positive note- the articles are generally interesting and reflect broader that the standard "centrist"-biased pablum that's spooned out on the more famous "mainstream" sites.
My biggest issue is the inept mechanics of trying to comment on an article: when you go to comments you get a pop-up page that covers the original article. If you want to check something in the original article before you sound off about it, you really can't without loosing what you've been writing.
For a site that strictly limits free views (2 per month) and puffs itself on its relevance, it's rather shabby to slip articles into the daily recommendations that are actually months or even years out of date.
