Here are the abysmal ratings for "Piece of My Heart." Apparently not even Kate Walsh could get viewers to return, as they mark a series low in ratings. Fortunately for us, the show is better than ever and still kicking everybody else's asses in the key demos! But, please, spread the word about how great the show is again and that they should watch it again! "Thanks" to TVGuide.com.

CSI trounced Grey's (albeit not in demos), 17.8 mil to 15.1 mil.

So, I have decided that, for those of you who choose not to visit the main site, I will go ahead and begin posting ABC's press releases here from now on - therefore letting you know all of the details on the episode without you ever having to leave this blog.
