A little frustration of reading our blog—or so we’ve heard from readers—is that it’s hard to keep up. No surprise there: In 2007, we posted around 290 pieces on the blog, more than one per weekday. It’s hard even for us to read ’em all.

So in the spirit of recycling, here are links to reader favorites from this year, as well as some of our picks for categories we created. Please feel free to add your own picks and pans in comments. And while we’re at it, thanks to our blog readers—some 200,000 of you this year—for reading, commenting, and keeping us on our toes. Keep it coming!
