This author doesn't inspire much confidence when he says "A fellow reader just forwarded this link to me" when referring to Google Closure. Did he even try it out? Also, some things are pretty pointless (e.g. "#6 - no globals" doesn't do anything to improve performance), and other are poorly explained (e.g. "#13 - store local refs to out-of-scope vars" - what does that even mean?) He even has syntax errors (e.g. "#7 - var fullName +=", really?) and other oddities ("#28 - element.bind" What in the world is that?) The good points are largely regurgitation of stuff that is much better covered by Steve Souders, the Opera blog and other resources.
