What's the Difference Between Facebook and Twitter?

Social marketing's all the rage. Facebook and Twitter and probably the most "famous" social marketing tools. Personally I avoid Myspace. If you're gonna use Facebook and/or Twitter to market your camp, the main points to remember with respect to their differences is that Facebook is best to communicate one-on-one with customers and prospects, while Twitter is better to speak to a crowd (as well as monitor what others are saying about you).
