It seems my notions about links are wildly unusual (and thanks Jules for adding them Wednesday). My idea is that since we're discussing science here, if you disagree with some point I make, or have a point to add yourself, then it is a good idea to include a link or full reference to a good source. One of the things about doing science is that you don't take people's reporting as gospel. Scientists are people, and people make mistakes. So it's a good idea to make it easy for people to check out the full original source. When you've described something well, they can be thankful for your much better description. Or maybe they can learn more about the topic. Wins all around.
Maybe there's something about how the blog world works that makes this a bad idea. If so, let me know how and why. In the mean time, please make it easy for people to follow up the science you bring up.
