I am not sure if this is in here...

but let me just tell one thing. The mobile part of my system is a hipsterPDA. One thing I have in it is a stack of cards with an ad-hoc presentation of my business cause. I always used to struggle with the "What do you do ?"-question. Now I can offer real insight for those who are interested. Or make some jokes for the people who just ask to keep the conversation going.
