1. I thought shorter = better in domain names. No?
2. It's an interesting point. Some think it's too much. Some told me it's too little. This covers credit card charges as well. Anything less than $1 donated is not worth it (hence why iPhone apps are .99).
3. By that reasoning any software should be free. But I would like to continue eating and sleeping in a bed at the same time.
4. Interesting point. I hadn't thought about it sending that message.
5. The research I looked at shows that if the company does a selfless act, their customers are more likely to be genuine in their acts. So, while you might give trash answers to get in to an iPad drawing, you're less likely to do that for the Red Cross to get a $1. Basically, people who like giving to charity typically aren't the type to give junk answers to surveys.
6. Response rates vary by industry. The university I worked at had a 80% response rate, whereas a local bank has a 10% response rate. So I tried to use an average response rate.
Thanks again for the feedback.
