I would enter this, but honestly, I can't pick just one. There are so many people deserving of being the 'BEST' of what exemplifies the Steem blockchain. Kudos to @smooth for putting up the cheddar and handing out the rounds. I'll drop a list of ten people here that I think are deserving though:

@snook - almost quit the platform and now is one of the premier video game and story-telling vloggers on chain.
@saffisara - giddy and upbeat and I don't think has missed a beat, she always comments and puts out unique posts.
@guiltyparties - though maybe not as talkative as some on chain, he has been here longer than almost everyone and still hustles to make it work.
@xcountytravelers - despite some health issues, they have been honing in on new steempeeps on an almost daily basis with very little recognition for it.
@shadowspub - one of the very first to have a radio show about the blockchain and has been curating and encouraging people to produce since I've known her.
@wesphilbin - his #thoughtfuldailypost encouragement really grips a heart, and he has a huge one in the face of his own issues.
@josephsavage - SBI has been one of the most stable and substantiating ways to help others and yourself grow here - guy is a genius.
@mariannewest - her #freewrite initiative has encouraged hundreds of aspiring authors to drop their 'writer's block' and has even spawned a few blockchain-written hard copy books.
@latino.romano - this guy is just as awesome as a person can be - and as dedicated as the power grid of a Venezuelan corrupted government will allow.
@jackmiller - this guy has a generosity and understanding that some people will never see in their lifetime - plus he's a nut.
