Some good posts to give you a feel for the blog include this one on instructional design and how to approach turning Powerpoints / Slideware from a classroom session into an online course, and this one about learning and memory. As you can see, the blog covers both technical how-to stuff, and more pedagogical material about how best to design and lay out material.
Seasoned online learning folks will probably roll their eyes. Where is the web 2.0 connectivist peer to peer learning and so on? This blog isn't for them. It's for people trying to get some fairly straightforward stuff done, using tools they are already familiar with. It's not going to bamboozle you with gee whizz. It's the kind of blog I'd like to produce, but don't have time, and since they've done an excellent job of it, I don't have to.
The Rapid eLearning blog is corporate, produced by Articulate, who make a bunch of eLearning tools. That said, the blog doesn't require or hard sell those tools, which is nice.
