I believe that EDN viewership is very non-hobbyist and very upper crust big company industry centric. Lots of old time fuddy-duddies been at the same company for 30 years, hence big numbers on the likes of the freescale 6800.
They also don't get huge engagement on their online stuff, so I reckon the poll result numbers would be low, which they don't publish. Wouldn't surprise me if they only got a few dozen people voting total.
