Laurie Penny is a British author and journalist, She is a contributing editor for New Statesmen and, as her website states "writes and speaks on social justice, pop culture, gender issues and digital politics for The Guardian, The Independent, Vice, Salon, The Nation, The New Inquiry and more."
She goes by the name Penny Red online.
UPDATE: And here is Abigail Brady, British writer and software engineer working in visual effects.
Mix one with the other and you get Abigail Beryl Burns, who goes by the name Red Peril online, and who just appeared in the last two pages of the rather magnificent Iron Man #18 yesterday, written by Kieron Gillen, and drawn by Joe Bennett and Scott Hanna.
So, you know, spoilers going on.
What does Laura Penny say? She seems rather happy…
Amongst the better things to happen this year: a character in the new Iron Man comic is apparently based on me. No, I haven't read it yet.

Glad we could help. And what does she become?
Iron Man does the Green Lantern Corps with Mandarin's rings folks! So, which other notable netizens could be next?
