Rob is a nice guy, but just not funny on the observation/ round up segment he does. He's much better suited to reading the tweets and emails, and at times seems genuinely funny there. Dump the "Look at me trying to be funny" bit and add more tweets/ videos, and all will be well.
I like Joe Swash, his enthusiasm makes up for him being about as funny as piles (when he's trying), and there are times when he's unintentionally funny.
