I wanna be a doctor!!!

The Dev Diary entry on day jobs pretty much confirms what I thought when I heard about the whole idea and gives a partial list of the benefits and accoladges are in the works.

I'm also really pleased that the 'On patrol' thing is 'in addition to' rather than 'instead of':

"In addition to all of the Day Jobs, every character is "On Patrol" after they log out of the game. When players log back into Paragon City or the Rogue Isles they will gain 1 bar of double experience (when defeating enemies) for every 24 hours they are logged out. A player can earn up to 10 bars of double experience this way. Double experience is shown as a blue portion of your experience bar."

And, they're talking about costume bits to correspond with the day jobs. Sweet!
