Still, why do those sites get so complacent? Seems to be the same with Twitter - maybe I am the only one using it via web, but they don't even have a tinyurl button or a search function for one's followers. What are they doing with their time?
I saw something similar with Heroku. In fact, in the RubyConf talk, Adam Wiggins pretty much stated that they were asked by their investors to switch gears to the making money part of things. Thus, the Heroku service stayed more or less the same (and good, I might add) for a period of time up until this recent announcement that other stuff had been happening behind the scenes.
I agree though, lots more they could do including a solid oauth implementation for the api...perpetually coming soon...
