Just like last year, here’s a compendium of math blog posts that inspired folks who were kind enough to respond to my carrion call. This isn’t an edublog award; it’s not a listicle. It’s simply a compilation of math blog posts that happened to find their way to my doorstep offered by peers who happened to find their way to my doorstep.

Feel free to download, edit, add to, and distribute to whom you see fit. Or just curl up with your favorite e-reader and some egg-nog.

One last imploration: please do follow the thoughtful blogs that are here. You’re seeing just a scratching of the surface with this text. Moreover, follow the folks who they follow. Because for every post you see here, there are dozens that are just as thoughtful and inspiring just a mouse-click or finger-tap away.
