I am too - if it isn't configured, I can live with it showing up until I go and set a preference saying 'Don't show this type of account in sharing options'. I get that they want it there so that people find it, but certainly asking not to show an account that I'm not planning on using (Twitter in my case) isn't too much? Or even just 1 option I can click that says 'Hide unconfigured accounts from sharing'. I'll certainly go file a bug report.
