If there's any part of the show that's the laziest, it's that one.
It's a case of: "Hey! Let's fill five minutes reading opinions from Twitter and Yahoo!"
I can see why you'd say its "lazy", but I think it's both funny and worthwhile. Highlighting the sort of brainless/xenophobic/Daily Mail-reading shite that infects pretty much every part of the internet (and indeed seems to proliferate only BECAUSE of the internet) never gets old.
