I happened across this cool customer-driven blog about customer service at everyone's favorite fast food chain-McDonalds:
It is not a blog that just engages in bashing what is amounts to a state religion in the United States and the rest of the world. It also highlights McDonalds restaurants that get it right. This blog also includes photos to illustrate its commentary.
Not to be outdone, joining the bandwagon of business blogs that are usually about reinforcing the "brand" of the company is McDonalds. Their blog can be found here.
