For much the same reasons. In fact, I'm not sure what the appeal is to so many people. When I first started reading it, it was to the story of how she became a rancher's wife and I liked her style of writing. Her poetry and one liners turned me off and then I never really read anything that hooked me back in.
But I think that happens to a lot of blogs, mine included. We start off in one direction, and then veer off when something attracts attention. I'd like to get back to my original style, but I've lost it, and now the kids could care less about reading what is going on in our lives.
The road to success is always under construction.
