The new buttons that could be rolling out have a flatter, and fatter look to them. It's not just visual changes though, the +1 button reflects the actual number of plusses on the post, which makes more sense than how it is currently implemented, and is more consistent with the mobile applications for both +Android and iOS. The new behaviour also affects the share button too, it's now faster to see how many +1s and shares a post has got now that the counts are on the buttons themselves rather than to the side.
|They're certainly bigger, but are they better?|
|When hovering a cursor over the button, it's looks strikingly like the new Google+ favicon|
Although the new set of buttons have yet to be confirmed by any of the +Google+ team, 1 or 2 other members in our community are also reporting the changes.
UPDATE: After being the first to report on this, it appears that lots of our readers are now seeing the change, indicating a full roll out.
