I thought I'd mention just because it was on the front page: my issue with AdWords seems to have been resolved. I have no clue whether it was an algorithmic hiccup or someone within the Googleplex actually noticing the issue, my support requests, or public disapproval -- as I noted in my update to the blog post, I have as much evidence for the existence in technical support in Google as I have evidence for the existence of Santa Claus. Luckily for Google, part of me still believes in Santa Claus.
Despite this experience, I would still recommend you use AdWords.
