Spotlight: Rationally Speaking
Rationally Speaking is the blog of Scientific Philosopher and Skeptic Massimo Pigliucci. It was running up until early-2014 when Massimo shifted his time to a new website, Scientia Salon. All the articles are still available for reading.
Massimo is a controversial figure in the skeptical world because although he doesn’t side with parapsychologists and paranormal proponents, his opinions are often in opposition to prominent skeptics, and he gets a lot of flak for it. While I disagree with some of his opinions the posts on Rationally Speaking are interesting, well-developed and logical. It is a great place to explore the why and how science works and the future of how science should work. If you visit be sure to pay close attention to the comments. There are great discussions!
