If you find Allsides helpful, that's ok with me. But their methodology boils down to what they call a "patented media bias detection and display technology." In other words, it's a black box. And the company is for-profit, so I assume they are getting paid by the sources they aggregate. Nothing wrong with that--it's true of any news feed. But I'm contrarian enough to mistrust someone who tells me they are going to rate for me how each article I read leans politically and present me a spectrum they consider "balanced." There are a lot of hidden value judgments implicit in their categorizations. I guess I'm more comfortable reading a range of sites that just admit they are trying to sell space for ads.
