I think that in the long run it is worth while to learn. I don't know how to do it, but I would love to know how to with my blog. Right now I've just been using a template. It's working out okay, but only because my blog is so new. I see all these cool blogs, and I wish that I had one like that. I think that the more you know about code and other things, the better you are able to make your blog. People like seeing that, vs some blog that is just using the same boring template as all the others. I notice a lot of WordPress blogs all use the same template. It makes me not want to go because they don't draw me in.
