Just wanted to share another great blog promotion tool - Feed Burner. This tool is a way you can share your blog feed across the board and will work with no matter what reader the subscriber has.
It is a great way to gain more exposure for your blog. For example here is the URL to this blogs feedburner to subscribe to: SEO Blog - just to get an idea how it works.
This is also a great tool to promote your podcasts as well if you are a podcaster.
