Dieter Komendera (via Allen Tan):
Apple just sent back my radar about t.co urls not working in Safari, saying it’s fixed in latest 10.11.4 beta.
It’s so great that Twitter decided to shorten every link posted to their service with their proprietary one, except for when
t.co is for whatever reason unavailable and none of the links posted through Twitter works. Also, this is a ridiculous bug in Safari that only affects Twitter, and I don’t understand that.
