We just got in a new book at the library called Blogging for Bliss: Crafting your own online journal by Tara Frey.
Tara takes you through Why blog for bliss all the way through If Emily Post(ed). I like this book because she talkes about Blogger, TypePad, WordPress and blogHer and has a how to on each one. She also talkes about adding pictures, widgets and html's. Tara included sites that demostrate how these all come into play to make your blog more interesting to readers and yourself.
If you get a chance look it over. It has good information for all bloggers.
