Salesforce.com and big names
Salesforce.com is great at attaching big names to their products or messaging. Anytime Benioff talks about their AppExchange product, he mentions iTunes. He does a very good job painting a picture of what the products do by pairing them with very well known products. That's why he's so successful.
