MyOpenID was down for me earlier today. I was greeted with this message (freehand circles for your viewing pleasure):
Next, I clicked on the StackExchange provider and found that the error message above lingers behind despite selecting a new and available provider.
Shouldn't the message be hidden unless the newly selected provider was also not found? That would be clearer to the user and prevent any confusion. Granted, this is a minor issue but it could be improved.
