Chet takes shots at Dan Bernstein ("gutless", "wimp", "look in the dictionary under 'bitch' and you'll find Dan Bernstein"), Julie DeCaro ("little tart"), Chris Rongy ("forever a recap guy, never a host"), and a guy downstate.
If you're interested take a look at the tweets at the link above.
I'm guessing Chet wishes he hadn't done it (which is why he deleted it), but the thing that seemingly (I'm guessing based on the article) sparked his anger (talking about the Patrick Sharp rumor with no substantiation) is a legitimate gripe. He could have addressed it without expressing his opinions quite so graphically, but Chet does have a tendency of going into full-Wrestling announcing mode pretty quickly.
The blog post suggests Chet was probably drunk when he did it, but I don't think he was. Chet doesn't drink.
(I interviewed Chet for the Illinois Entertainer last May)
