Most of the conferences I attend are helpful and only sometimes they are inspirational. The Salesforce.com conference this week was absolutely in the latter category.  There were several product announcements including Force.com sites which let you build websites on their platform, along with integrations between Force.com and Facebook and Amazon EC2.  But beyond that, one of the use cases for Sites was created by rock alum Neil Young, who took the stage to talk about his Lincvolt site, then wheeled out a classic American 1959 Lincoln electric-naturalgas hybrid. Here was a SaaS solutions vendor taking time to talk about one of their rather famous customers, with a project so meaningful that it could help change the future - now that’s inspirational.  Okay, and Foo Fighters were fun as well.
