Twitter tells third-party devs to stop making Twitter client apps – "More significantly, it demonstrates the vulnerability of building a business on top of a Web platform that is controlled by a single vendor." This is exactly the lesson I found with my Delicious.com client.
Deliberately uninformed, relentlessly so [a rant] – "Many people in the United States purchase one or fewer books every year. Many of those people have seen every single episode of American Idol. There is clearly a correlation here." Wholeheartedly agree with this post. Not knowing stuff is fine. Being proud of not knowing stuff? Not so much.
Twitter Can Predict the Stock Market – "Mao compared the national mood to the Dow Jones Industrial Average. She found that one emotion, calmness, lined up surprisingly well with the rises and falls of the stock market — but three or four days in advance."
Compromising Twitter’s OAuth security system – " What it comes down to is that OAuth 1.0a is a horrible solution to a very difficult problem. It works acceptably well for server-to-server authentication, but there are far too many unresolved issues in the current specification for it to be used as-is on a widespread basis for desktop applications. It's simply not mature enough yet." This is pretty much what I found implementing OAuth for Yahoo! in Yummy.
