The internet is a great resource. But it can also be a scary place unless you have some good filters separating signal from noise. The following links are to people whom I have come to trust as great filters of the vast amounts of information that is available online. I might not always agree with everything they write, but I trust them in their critical and balanced thinking. If you are looking for anything from a “how to” guide to this whole paleo gig, to a better understanding of your inner workings, then these are the people I look to for top-notch information.
For those wanting some well-balanced information on the effectiveness of various supplements (not paleo, but people still ask about this stuff), check out Examine.com
