Foursquare co-founder encourages users to wage war on Chipotle

In case you haven't heard, homegrown chain Chipotle Mexican Grill is offering a Facebook deal this weekend whereby if you "check in" using Facebook Places Mobile on your smartphone and show your phone screen, proving that you're not a big, fat liar to the eye-rolling workhorse behind the register, you'll get a buy-one, get-one free burrito, burrito bowl, salad or order of tacos.

But the deal, which kicks off tomorrow at noon and continues through Sunday evening at every Chipotle in the country, has pissed off Foursquare co-owner Dennis Crowley, who took to his twitter page earlier today to denounce the deal and instead plead with Chris Arnold, Chipotle's director of public relations, to spread the love -- specifically to offer a Foursquare deal instead.

Here's what Crowley had to say:

And while Chipotle's Facebook page is littered with comments from those who can't wait to wrap their jaws around a seam-splitting burrito (some are even vowing to hit up every Chipotle in town), others, like "Anna," write:

I love chipotle enough to do this, but I'm not a huge fan of Facebook Places, I much prefer Foursquare!! How about next time?!

And on Arnold's Twitter page, someone else quips:

I hate FaceBook (privacy issues). But I love FourSquare. What about me?!?!"

At the moment, you're SOL, but Arnold isn't averse to a future Foursquare promotion:

"Just FB Places this time, but let me hear from you #foursquare fans and I'll plead the case," tweeted Arnold earlier today.

You can bet that Crowley is waiting with burrito bated breath.
