3M: An old company working at the speed of Twitter

A few hours ago I tweeted a random thought I had about Post-It notes and my iPhone:

3M should make a Post-It that fits exactly on the front of an iPhone. The one's in my office are slightly too big.

Within two hours 3M had @replied to me with a suggestion from their product catalog that would fit on my iPhone:

Hi John - you might be interested to try this size. let us know how you get on http://tinyurl.com/a67xqh

Nice.
