Here is a crowd-sourced selection of some of the inspiring, creative and touching math blog posts from 2012, my **Math Blogging Retrospectus 2012**. I asked for some reading material over winter break and colleagues commented on some of the math blogging material that stuck out to them in 2012. Here are those blog posts collected and aggregated in one single document.

Obviously there are drawbacks to a static medium such as a document, but the hyperlinks are still good so you can click and explore each post in its original Web 2.0 glory. Perhaps downloading it to your favorite e-reader might be a decent way to take in this mammoth archive of mathy goodness. Otherwise, you could sneak into your school’s work lounge late at night and use up your school’s precious paper and ink toner like crazy.

I’d like to point out: **this is just the tip of the ice-berg**! It’s merely a collection of posts from people who *happened* to come across my post in a *week span* and *happened* to comment or tweet me. There are hundreds of other great posts and authors of posts. This is a start, it’s not comprehensive, let alone exhaustive.

Thanks to everyone who submitted the blog posts, and of course to those who wrote them.
