Uninstalled and reinstalled Twitter (though I think a clear data would probably work too)
Did NOT open the Twitter app or add a Twitter Account through settings
Instead I went into Blinkfeed -> Topics and Services -> Services & Apps and clicked on Twitter
Get prompted to enter uesrname and password
Then get the Authorize Twitter for HTC Sense screen et viola Twitter is back in Blinkfeed
