Knitting and Blogs?

This isn't going to be a rant. As a matter of fact I've enjoyed many of the blogs I'm about to speak of. What the fuck is the deal with the disproportionate amount of knitting blogs? I haven't happened upon any that ONLY write about knitting, but many of the blogs I run into have at least a small portion dedicated to this old lady's pastime. Why is that? Are knitters early adopters of technology by nature? Or do writers just need something else to do with their hands? I don't get it.
