Submit Your site to Directories
There are many directories to choose from and you should spend some time submitting your site to them. I have a free directory @ Free US Directory or if you have an industrial site I have a Premium Industrial Directory.
The problem with submitting to directories is that the take a lot of time. A site has streamlined this process. http://www.easysubmits.com/. You enter your information and category and then simple click on each directory that you want to submit to, I did about 200 directories in 2 hours.
I normally run my rss feeds through feedburner and then take the feed and submit it to rss directories. There are a lot of them just Google rss directory. Once you have about ten good posts then make sure to submit it to Technorati.com. That is a poplular place to discuss blogs.
That should be enough to get you started.
