She doesn't affiliate herself with the skeptical movement, but she is one. Don't believe me? read anything she writes about here http://www.regretsy.com/category/bullshit/
This is a wonderful story, and I'm glad you linked to it, but I think it's a bit of a stretch to suggest that referring to Tarot card readings for cats as bullshit qualifies her as a skeptic. It's certainly a lot better than her believing in tarot card readings for cats, of course.
Still skeptical about Hellen Killer being a skeptic huh? Read this 1000 word tirade from Jackie Stallone (Yes, Sylvester's mom) titled, In Defense of Rumpology http://jstallone.hubpages.com/hub/In-Defense-of-Rumpology
Seriously, this lady thinks she can read peoples asses and see the future http://www.jacquelinestallone.com/rumps.html
She's a known quack and frequent punching bag of skeptics everywhere, but for some reason it was this story on regretsy that got her all frothed up:http://www.regretsy.com/2011/07/20/crack-head/
So Jackie Stallone decided to threaten regretsy with legal action if they didn't stop making fun of her for saying she can see people's futures by reading their behinds.http://www.regretsy.com/2011/11/14/stop-or-my-mom-will-shoot/
I'll even do a seven degrees of skepticism.
Hellen Killer who runs regretsy is in real life April Winchell
April Winchell was the voice actress who played Mrs. Finster in the Disney cartoon Recess
If you remember the show, Mrs. Finster had one kid who was her pet..Randall
Randall was voice acted by Jarrett Kaufman
Jarrett Kaufman plays Timmy on Mr. Diety and is on the steering committee for the Independent Investigations Group.http://www.iigwest.com/
