Ad sense?

I've been contemplating trying to make some money off this thing. It certainly would move me to write some more. I've checked a few other blogs and see that some of you are using Google's Ad Sense program and one or two have more specific ads.

I have a few questions:

People with Blogs that have ads: How much are you making? Roughly? Is it worth it? Any suggestions?

Readers: Is my blog being Ad-Free an important factor? Will you be totally turned off and accuse me of "selling out" if I put Google's Ad Sense into my blog?

I'm leaning more towards Ad Sense. When I've seen it in people's blogs, it looks pretty unobtrusive.

Let me know what you think by email or comment below.

Thanks,
