I remember when I could find real science online. It was easy. Sometimes I had to translate it from a foreign language. It was raw science directly from the source, unfiltered.
Written by scientists for whomever it concerned. Not political pr. Fictions.
But that's just one example. It's like there's a huge filter hiding 99% of the real Web.
