theodp writes "With his Khan Academy: The Hype and the Reality screed in the Washington Post, Mathalicious founder Karim Kai Ani — a former middle school teacher and math coach — throws some cold water on the Summer of Khan Love hippies, starting with U.S. Secretary of Education Arne Duncan. From the article: 'When asked why so many teachers have such adverse reactions to Khan Academy, Khan suggests it's because they're jealous. "It'd piss me off, too, if I had been teaching for 30 years and suddenly this ex-hedge-fund guy is hailed as the world's teacher." Of course, teachers aren't "pissed off" because Sal Khan is the world's teacher. They're concerned that he's a bad teacher who people think is great; that the guy who's delivered over 170 million lessons to students around the world openly brags about being unprepared and considers the precise explanation of mathematical concepts to be mere "nitpicking." Experienced educators are concerned that when bad teaching happens in the classroom, it's a crisis; but that when it happens on YouTube, it's a "revolution."'"

TropicalCoder writes "Ray Ozzie says that Google Wave is 'anti-Web,' by which he seems to mean that it is too complex for its own good. In the video he complains about its complexity in relation to Microsoft's Live Mesh: 'If you have something, that by its very nature is very complex, with many goals... then you need open source to have many instances of it because nobody will be able to do an independent implementation of it.' That's its weakness to Ozzie, apparently — that this complexity that can only be overcome by open source. While he heaps high praise on the Google team that came up with this, he feels that the advantage of Microsoft's approach is that '...by decomposing things to be simpler, you don't need open source.' The Register's author summarizes it like this: 'In a way, this is classic Microsoft meets what is emerging as classic Google. Microsoft gives you an integrated stack but all the moving parts are anchored on a single company's vision. Google frees you to work out the bits yourself, but you must rely on your own smarts or those of your chosen tools.'"
