Ad words - the magic of add placement within your blog

Hey, we are thankful to Google, of course for giving us that space to tell everybody what we think and what our business is currently all about. But what about the automatic robot that sorts through the postings - he/she must be rather clueless what type of people browse this blog. Last week they (are they only one or do they have seperate identities?) wanted to sell of tires (usually I use my bike) and then they offered free Tarot readings and magicians to cure whatever problems you have...and now they even switched to advertisments for local food. What a difficult life this robot must lead, we pity him/her don`t we?
