"I'm definitely trying to holler at Tina Fey," Diddy told E! in a December interview. "Me and Tracey [Morgan], we've been talking, and we got a scheme up our sleeves."
"I'm definitely trying to get in on that in the next two years, for real," he said.
"'30 Rock' has become a cool destination for someone who wants to get an Emmy nod," said TV Guide's Roush.
In 2008, seven of the 10 Emmy nominations for best guest actor or actress in a comedy series were for stars who'd made appearances on "30 Rock."
"It's a guest spot that really pops and people take notice," said Roush.
While no television guru was willing to say that ratings don't matter, the critical acclaim "30 Rock" has received may have secured the show a spot on NBC's future lineup.
"I'm not sure if the show has potential to become a ratings hit, but I don't think that an issue," said Roush. "I don't think it needs to be."
"For the prestige '30 Rock' brings NBC, through the awards and having someone like Tina Fey who is so in the media spotlight, it doesn't matter what the ratings are. It just helps the network," he said.
"The best thing for "30 Rock" in terms of what NBC can do for it is have faith and give it time," said The Hollywood Reporter's Hibberd, who also writes the Live Feed, a blog on all things TV.
"Sitcom ratings, especially ones that bring something unique to the table, tend to improve with time," he said.
Shows like NBC's "The Office" and CBS's "How I Met Your Mother" were both barely renewed after their first seasons, said Hibberd, but are now considered valuable by their networks.
"Yes, the jokes on shows like "Two and a Half Men" are probably more universal and gettable than the jokes on "30 Rock," said Hibberd.
"But that doesn't mean "30 Rock" should try to change its stripes."
