Salesforce.com and RSS
Charlie Wood has a great example of enterprise RSS up and running in his Spanning Salesforce application. He’s gotten good buzz around it, even without putting out a press release. Consider it an early example of combining RSS with an API to get data enterprise data from a hosted application via RSS.
Simultaneously, Ryan Martens pointed me at the new Salesforce.com CRMSuccess.com blog. Built on top of Typepad with the feed by FeedBurner, this is an outstanding example of an enterprise blog that highlights a specific application (in this case – Salesforce.com) as well as “best practices” for this application (in this case – CRM).
