The Time 100 is a pretty big deal, as the world's most recognizable magazine calls attention to the most influential people in the world. While she was already part of a Top 100 People on the Internet list from the organization, Anita Sarkeesian has now been drafted onto the overall Time 100.
In a a forward written by Wil Wheaton on Time's website, he concludes:
Anita is a feminist for the digital age, using modern tools and platforms to engage thousands of people who want to hear her thoughts and respond to the challenges she raises. A lesser person may throw up her hands and unplug her game console, but Anita is determined to ensure that video games are inclusive and representative of everyone who plays them. As her detractors grow increasingly unhinged, we have proof that her efforts are working.
This is obviously a pretty controversial pick by the magazine, but I don't feel it is unwarranted. Regardless of where you fall on your opinion of Sarkeesian, I think it would be tough to deny her influence over video games over the last year or so. I personally value her incite, even if I find myself disagreeing with her at points.
There is at least some irony here that she almost certainly wouldn't have had such an influential rise if it weren't for such a vehment backlash against most of her tame and reasoned criticism.
