From what I can see on the presentation that he links to, there's nothing to warrant the 10x more productive claim. Perhaps he's just doing a bad job of explaining the secret sauce, but I mean really? Shit like: bind("tip", xhtml, "done_checkbox" -> ajaxCheckbox(userStatus.equals(Full(TipUserStatus.done)), (b: Boolean) => { val currentUser = User.currentUser.open_! val evertodo = TipUserBind.find(By(TipUserBind.tipid, this), By(TipUserBind.userid, currentUser)) match { case Full(tub) => tub.delete_!; true case _ => false } makes you 10x more productive? The spreadsheet is also just for JVM frameworks, although some of them are probably MVC too, it's hard to tell. Also, you can really tell that both the parties involved come from heavy corporate backgrounds, with massive tables of features and rating them against each other. A scale of 0, 0.5, 1.0? And then the Lift guy switches to /11? Give me a break...
