We don't mind the change of link - we just want knowledge shared on Quora to get to as many people as possible and we don't mind if it happens on other sites. But I wanted to let you guys know that this was a bug and the behavior is back to normal (nothing with share=1 will ever require viewers to sign in / trigger this level of complaints). There can be so much negativity here that it can be hard to tell the difference between general hate (as radmuzom suspected) and a real problem, but in this case it was a real problem.
