I shared something with the Blur-it bookmarklet that I’d like to remove, but can’t figure out how to remove it now. Ideas?
Open your blog in the app (i.e. use the "View on Newsblur” link under the account menu on your blurblog. Your shared item feed should include the item in question and the context menu will display “Shared” where the “Share” option would normally be. Clicking on that will allow you to cancel the share.
