Once you have an established blog, then you’ll want to get it listed in blog directories.
You’ll want to learn about Technorati 884G69W7NRTY and Pingomatic, as well as several others. There are even things called Blog Carnivals.
After you have about 5-6 entries in your blog and I hope you’re blogging beyond just what I suggest here, then you’ll be a prime candidate for this extra publicity push.
Just some food for thought, and something to file away for future use.
