Visit e.g. http://www.theguardian.com/artanddesi… and attempt to use the share bookmarklet. The title will change but the sharing dialog will not appear due to an exception raised in the bookmarklet’s code:
My current workaround is to use the developer tools to disable JavaScript, reload the page, enable JavaScript and use the bookmarklet. I think it’d make more sense to focus on adding the ability to share URLs in Newsblur instead.
