Alright, so this one is not quite like the others. But if reveling in fandom is as fun for you as it is for us, we think you'll like these guys. They are John and Hank Green, and they have devoted their lives to making awesome things for us to watch and read. Beginning their vlogging time in 2007 when they decided to go a year without textually communicating with each other, the Vlogbrothers (one of whom is a New York Times best-selling novelist) have since been steadily growing their following to monstrous, inspiring proportions. Their fans are called Nerdfighters, and they even do things like flash their hand signal at the Olympics.
So how is this at all relevant to helping you get through this Sherlock hiatus? Well, in some roundabout ways as well as some slightly more concrete ones. Take this: I (Alanna) saw Hank Green in concert the other day in Portland, and during one of his songs he referenced Benedict Cumberbatch. The roar from the crowd almost took away my hearing it was so passionate. If you are reading this, their people are probably your people.
John and Hank consistently make hilarious, heart-touching, and incredibly intelligent videos. Whether it's just them in their basements talking into a camera, the songs Hank sings, or the books John writes, in my humble opinion it is all worth your time. They've also posted about a zillion videos, so if you watch all of them (which is not at all required), it might just take you from now until when The Hobbit finally wraps filming.
You should also consider the fact that the Green brothers talk fast and will feed your brain; it's always nice to add more of that to your life, especially when Sherlock himself isn't there to take us to his mind palace.
