Things I miss about the third season of 30 Rock

Having re-watched a couple of the first and second season episodes of 30 Rock, I've found that the show feels different this third season. Here's what I think is missing:

• Jack as detached boss instead of friend to Liz
• Trailing subplots that never get wrapped up
• Where did all the other characters go?..... i.e. I need more:
  
• Jonathan!
  
• Pete
• Frank & Toofer
  
• Conan

That is all. :P
