New Product: I am very excited by the Square credit card processor for the iPhone (and maybe other devices with an audio plug).  This product will revolutionize the way that people can conduct commerce.  Not just businesses, but even person to person.  The device is a small square credit card reader that plugs into the audio jack on the iPhone.  There is software for the iPhone that will process the credit card and transfer money directly to the recipient’s bank account.  Now the founders of Square have done some things right.  They priced the software at $1 and the device is free.  This makes it almost irresistible for anyone who wants to accept credit cards.  Think of craft fairs, your lawn mowing teen or a Craigslist seller. The cost per transaction is reasonable (2.9%) and Square will even donate a penny per transaction to a charity of your choice. More details and a video here.

Knowledge: Steve Schwartz wrote a post on the 3 types of knowledge. While the language is not always appropriate for elementary school, he does explain clearly how these 3 types contribute to our general sense of ourselves.

Advice: Micah writes about giving advice. This one is going to be hard for me to do (given the name of this blog) as I love to give advice almost as much as Micah does, but if he can find a better way, I can try.
