Rebecca Watson blogs in the Skepchick blog network, which she also runs, and she also appears in the online radio show The Skeptics Guide to the Universe | Your escape to reality.
She has become a central figure in the Misogyny Wars as a result of the Elevatorgate scandal. In June 2011, at 4 am in an elevator far away from home, some "gentleman" asked her if she wanted to go to his room and have some coffee. She vlogged about that incident, concluding with "Guys, don't do that". That provoked an extremely vicious, hostile response, almost as if she had committed some terrible atrocities against the "Elevator Guy". She has continued her feminist activism, taking a swipe at evolutionary psychology in her talk How Girls Evolved to Shop.
She has an asteroid named after her.
