Yesterday I noticed that the MyOpenID sign-in UI has changed. Gone are the multitude of buttons and the paragraphs of gobbledegook. Now it's just a simple question — do you want to sign in? — and a huge "Continue" button. The SREG UI has also been refined. This makes me happy, because I've always thought MyOpenID's SREG UI was a bit... scary. Now it's been reduced to just a drop-down list to select which persona to use, though the option to view the details is there if you want it.
This seems to me to be a much better way to present things. No functionality's gone, but the amount of visual noise on the page has been reduced to the bare essentials. Good stuff.
