I foolishly pushed the vote (near most recent) in idbruce's discussion of votes and now I can't see any discussions. I tried:
restarting safari (iMac 10.10.5)
restarting iMac (didn't really expect that to help)
clearing history (really thought that might work)
Re-inventing the wheel is not a waste of time if, when you are done, you understand why it is round.
