Here is some of the things I have found:
The Mudville Gazette has Ten really good tips for beginers: Everything You Always Wanted to Know About Blogging
Harvey at Bad Example has his 12 steps to better blogging
basil is on part six of his series Learning to Blog based on some of Harvey's work: Learning to Blog VI: Google Search Code
Ambra Nykol is also on part six of her series "How To Blog Like a Rockstar"
Phin (BTW he has a new address) and Confederate Yankee have established a site just for new bloggers: Blog Netiquette
All of these resources are good. They have made me a better blogger.
