I noticed a strange book on my del.icio.us bookmarks that made it possible for the same URL to display a different webpage by clicking on different links to seemingly the same page. I’d written to tech support about this a few weeks ago, but I got a quicker response when I attached a screen print showing the odd behavior. Nick, the a Product Manager, quickly figured it out and wrote “you found an interesting bug and I think we got it nailed. Thanks for responding, it really helped us out.” Quite satisfying!
