Well, here are my two favorite websites. On top of the list (a huuge list of only two links xD jaja) there's the Plain English video, personaly I love their material and the way they explain such kind of things. The second one is the E|FL 2.0 blog the reason? I think it's really cool and full of nice advices and aplications for your blog!!!
Which are your favorite sites?
