The more I learn about this coding stuff, the more dissatisfied I become with the default ways that things work with the various themes. With that in mind I'm giving serious consideration to giving myself more customizing power with either the CSS upgrade or moving to a self-hosted blog. I'm hoping that someone can point me to some good discussions comparing the potentials and pitfalls of the two, as well as any alternative(s) I don't know about. I'd list some of the things I'd like to change, but posting such a long list of questions seems inappropriate.
Thanks in advance.
The blog I need help with is iwanticewater.wordpress.com.
