Well, East Side Dave is apparently a Sirius/XM guy with a truly horrifying website:
http://www.specialdeliveryshow.com/. Also, it's called 'Special Delivery With Sam and Dave', which don't call yourself that unless you had a string of R&B hits in the 60s. Fortunately, his fans can't decide on what his Twitter handle is, so he's Peroting himself, siphoning off valuable votes that would have otherwise gone to him.
East Side Dave is also quite possibly the worst Twitter user ever.
huffstapes is apparently a 'drive time comedy show in podcast form'. They do have a very nice website, unlike Eastsidedave.
http://blog.huffandstapes.com. Apparently the show also features Poker, which I can't abide in any form, podcast, TV, book, live.
Finally Big O and Dukes - with a name like that we don't really need to investigate further.
In conclusion: vote for @scharpling. we did it for @tedleo, we can do it for @scharpling. None of these other shows' fans can agree on a spelling, so that should help some.
