I'm a huge fan of avantgardevegan, Forks Over Knives, CookingWithPlants, MicTheVegan, Nutritionfacts.org, and many many more. YT is probably one of my greatest resources for recipes and on-the-fly info.
I love Pick Up Limes, Mary's Test Kitchen, and Cheap Lazy Vegan. Avantgarde Vegan was mentioned earlier - he's fun to watch, too - but man his recipes are usually too fussy for my level of patience (but I'd love to EAT anything he makes!)
I find Unnatural Vegan interesting at times. Sometimes I get tired of her continual MO of debunking everything (be it vegan or not), but oftentimes she has a lot of good points.
Finally, I like John Venus. I enjoy watching the male perspective of vegan fitness over female (maybe it's just because he's pleasant to look at, lol.)
