While the author has a right to be upset, her attitude toward the support staff — who likely have no control over the situation — is disgusting. ("Your apology is worthless", "Your refusal to check the link", etc. from the email conversation, and the ensuing comments on the blog post.)
Anyway, this is quite an eye-opening article. What bit.ly is doing is a great example of how not to run a business. We should be educating people about the internet, not taking advantage of their ignorance so we can lie about our competitors.
