Working with Ads

I'm adding some...uh...ads to the blog. Not looking to get rich... Ok. Hoping, but not looking... Anyways, I want to try to add to the experience and keep things unobtrusive. Nothing worse than huge glaring ads in your face to take away interest.

I'm no expert in the matter, so it is a learning process and I'll be testing the waters with a few things I suppose. First up: I've added some convenient Amazon links to purchase books on the book reviews (not cutting edge, I know. But a start). Plus I put the prerequisite google AdSense text ads. I've looked around to see what else is out there and for now that seems sufficient.

So if you want to support me in my writing habit you can click to buy an advertised book or check out one of the ads.

Any suggestions or thoughts as to the inclusion? Is it enough? Too much? What else should I do?
