I’m going to give you a few blogs I love off the top of my head:
adventuretitanbetty, seriously she’s an amazing analyst and a must follow for any AT fan.
saiyanshredder, he loves AT, and he makes a lot of cool AMVs and some not so cool puns… XD
sushiprincessss, speaking of AMVs, I highly recommend you check out this guy’s Youtube by the same name and watch AMV Nightosphere.
the-piedmonbetty, an excellent AT blog to follow, especially if you love Simon Petrikov.
Randomrainibettycorn, she has a great blog that also dabbles in some non-AT related posts, but most of all she’s an awesome person that’s be more than happy to get to know you and help you feel welcome in the fandom.
kasukasukasumisty, an awesome person who happens to share my favorite character, Finn.
bulletpainpills, a must follow for any Flame Princess fan.
Again this is just off the top of my head, and there are way more awesome blogs to follow that I don’t have the time to list.
I highly recommend Saiyanshredder’s fan lexicon if this isn’t enough to satiate your thirst for AT blogs.
