Risers, track drops, flats, carbon, aluminum, narrow, wide.....Chicago style.....bum bars.  At least that is what we always called them growing up riding BMX.  It looks silly, quite frankly.  Somebody riding an old road bike down the street with the traditional road drop bars turned upside down with the brake levers facing backwards.  But, now that I have been riding my Bianchi for half a year I totally understand.  Raising your hand position makes for so much more of a comfortable ride.  Now, granted, I will not be flipping the bars on my cyclocross bike up, but it is just amazing how a riding style has changed my outlook on cycling so drastically.  I own 5 bikes and each has its' own very specific purpose.  My touring/commuter/pourter racked slow poke bike does everything I need a bike to do but go fast.  And my other bikes serve that purpose quite well.  So, here is two cheers for the weird guys riding down the street with their handlebars upside down.  Horray for being comfortable.  Horray for not caring how silly it looks.  Ride your bike however you choose.
