At some point today, did you roll out a change to the tweet button script? If so, it is causing all sorts of wacky rendering issues when placed alongside other sharing buttons like Facebook, LinkeIn, etc.
For example, look at how it collides with the Like button on TechCrunch: http://techcrunch.com/2014/02/05/media-queen-gerry-laybourne-joins-betaworks-board/
I’m seeing this behavior on 3 sites that I manage that implement the tweet button. Please help or roll back if there was a change today.
