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. I've got just a few weeks open between now and July and much more availability in the second half of the year. If you're interested, send me a note.
