It was brought to my attention by J. that there will be a full set of 12 Mythbusters stickers this season! This post from Discovery's blog notes "You’ll also be one-step closer to earning a special set of MythBusters stickers for tuning into all 12 episodes of the new season as they premiere each Wednesday!" This wasn't mentioned anywhere on GetGlue's blog. It was, however in the Twitter feed as a reTweet from Discovery Channel. One would think GetGlue would want an announcement of that type on their blog feed.
Regardless, I've added Mythbusters to the reminder calendar. Even if you weren't able to get the Premiere sticker, keep checking in to get the rest of the set!
