I didn't think this post was out of line with the rest of Steve's blog. Steve does write about a lot of different things. I may be wrong about this, but aren't some of his most popular posts the ones about getting traffic to your blog, and making a living from your blogging? Not exactly "pure" personal development posts, but I know that I found Steve's blogs as a result of these posts.
And of course, the old adage ... you don't have to read it if you don't like it, and you don't have to click on any of the links if it doesn't appeal to you.
