Ads, yay or nay?

I’m toying with the idea of running some ads on this site (maybe just Google AdSense or whatever Yahoo does, I’m not sure) but if a large group of regular readers hates the idea, I probably won’t do it. So, I’m curious, would you find a few ads on this site extremely irksome? Or would it not really matter? Let me know in the comments, or just e-mail me. Thanks!
