Salesforce.com joins the ranks of IBM, Cisco, Microsoft, etc. in bringing social networking, popularized by MySpace, to the corporation. AppSpace is to be an interaction space for customers, with ties to AppExchange. Launched at the beginning of this year and now just a showcase for applications, AppExchange is scheduled to be a fully functional marketplace for applications by the end of the year. AppSpace will permit the sharing of applications acquired from AppExchange, and expected social features include collaboration, blogs and wikis.
