Just Smashing!
Smashing Magazine offers a service I haven't seen before. They post the best links, articles, tutorials, and more that are all about web development. But they look back at the previous month's top resources, so that you can catch up on what you didn't see the month before. Very nicely done, it has a friendly interface and I love that there is no shame in the fact that you didn't read these items the millisecond they appeared online.
