Does anyone out there currently use a blog to promote their affiliate ads?

How's it working out? How long have you been at it and how successfull have you been at it. I currently have a blog promoting my online venture but I'd like to get into affiliate advertising as well using my current blog. Any thoughts, tips, pointers.

REAL NUMBERS HERE WITH NO B.S PLEASE.!

I am not comfortable with releasing numbers, however I have had continuing success using Squidoo. It is free, and most of all simple.

I have created a site to help others to understand how to get started and how it can bring some income in over time and dedication.
