Yes, Ellen slayed all the promotions for the 300th! Soooo proud!
Honestly, those who tried to diminish what an amazing milestone this episode was for her never really cared about her as an actor or Meredith as a character at all. Which is so disrespectful to the legacy of MerDer ... Meredith is half of that equation and those who lost interest, purposefully boycotted, or slandered her story the very minute she was tragically alone didn't love her as much as Derek did. That's for sure.
