I love Daniela Titan's fun and informative science videos on YouTube. You can also follow her on Facebook and Twitter.
A note to all my geek girls: I love you ladies. I know it's been a rough month & we're all tired. Still, y'all keep going & that's amazing.Geek Girl Diva: blog, Facebook, Google+, and Tumblr.

Mz Maau is one of my faves on Google+. She's always got some great links and commentary. She also collects great videos on her YouTube channel.
Princess Mentality Cosplay is full of fantastic geeky cosplay! She can also be found on Twitter.
Whenever I need a hearty dose of kickass women doing kickass things, I check out the images on FuckYeahCollegeSoftball's Tumblr page.
