Google Adsense makes my brain hurt. The best (and only) way to promote your company, product, app, or service to the MacSparky readers is through a week-long sponsorship. What do you get? An exclusive ad in the right margin and a post in the RSS feed. I only take one advertiser a week. My readers are smart (and some of them have no respect for money) so why don't you reach out to them directly? To learn more, send me a note at email@example.com.
