When I saw that my posts continued using TinyURL, I disabled the TwitterFeed service and did some research, where I found out that your API Key is not the same as your password. As one of the more technically- and detailed-oriented people I know, I should have realized this, so shame on me for that. However shame on TwitterFeed for not taking the two hours to create an inline explanation of what an API key is (or the two days to create robust inline linking to all of the URL shortener services API key pages so that the user could get their key without ever leaving the TwitterFeed site). If I was this close to dropping their service with my top Computer Science program degree and career spent in IT, imagine how many ordinary users who encounter this puzzle must simply decide the service is not worth the effort. Even worse, a simple search on their support forum shows that many others have complained about the same problem and even gotten replies from TwitterFeed employees, so what are they waiting for to fix the problem?
