Schwartz also emphasized the importance of safety.
"I really think that people should go on a dating site," Schwartz said. "Places that are anonymous can overattract people who want that anonymity, and I would be very cautious. Do your due diligence before you even meet the person."
Schwartz said the experience might even be good for singletons to get into the practice of being with a partner.
"I don't think it's bad, but it's not the best thing you could do for yourself. You could do better," Schwartz said. "I do think it could cause someone to say, is this really where I want to be in my life?"
The women behind "Two Girls, One Season" have been posting some of the responses they say they've received on the blog.
"I will play the part flawlessly, and I will stick to my end of the deal even if we end up not liking each other. Knowing that - if chosen - this would end amicably on a specified day is about the most comforting thought I've had in a while," wrote one potential suitor. "This sounds like a pretty fun experiment; it's like a one-man flash mob."
"We're in NY but self-employed so traveling is no sweat, especially taking a couple weeks off for a "Love Actually" re-enactment," read another response.
One of the messages was signed, "Everlasting temporary love, Holiday Hunks."
It sounds like the beginning of a beautiful, if fleeting, December-December romance.
