One of the things that has made Dell World very different is that at the end, one or more controversial speakers take the stage and provide an incredible amount of insight for the folks who haven't left early. All three of the last three speakers were fascinating, but it wasn't until I wove all three speeches together that it became clear to me why innovation seems to evaporate the larger a company becomes. I was drawn in particular to why Netscape failed and Google, outside of ad revenue, largely has been unsuccessful.
