I think Mixpanel should invest a serious effort into creating some tutorials on how to do event tracking in a way that helps your business. I suspect a lot of more people would use the service to its full potential if they knew how.<p>Even showing off some customers setups that are using it well would go a long way.<p>A good example of where this strategy helped the business is Slicehost's Linux tutorials.
I was hoping it was an ML article on data segmentation techniques, but it looks like it's just a web service announcing that they've improved their filtering options. :(
