The Tumblr universe is vast. From the endless GIF blog nebulas to the ever-expanding galaxies of nail art, it’s a sprawling, mostly unnavigable, awe-inspiring mess. How to find the meme-iest gems, or at the very least some face-melting photos? It’s been two years since I shared my ten favorite Tumblrs of 2011 (thanks for reading it 250k times- yowza!) so this list is pretty damn overdue. This time I thought I’d start early in this banner year for Tumblr, and update the list as I find new gold. If the Yahoo acquisition does end up being the moment Tumblr jumps the shark, well, hey – here’s the final batch of awesome, Golden Age Tumblrs.
