I bet you didn’t know that today is Apple Pie Day? Oh, wait – you did? Well, how patriotic of you.

In order to celebrate this great day for our union, breakfast superstars Dunkin Donuts is running a contest on Twitter to give away $50 gift cards to its followers. Using the hashtag #ApplePieDDay, tweet your guess for the types of apples Dunkin uses in its apple pie, and you could win.

Make sure to get your guesses in by 1 pm. Of all the correct applicants, the winner will be selected at random at 1:30 pm today.

Dunkin Donuts is on the leading edge of social media-connected food chains. The company’s Twitter account has around 80,000 followers and is very well connected with them. Just in the last day, the account has publicly replied to around 20 different followers. The company frequently holds contests and promotions via Twitter, so many that is has an entire page on its site devoted to “rules for contest on social networks.”

In April, Dunkin Donuts retooled its website to be more focused on social media, integrating live Twitter feed as well as Facebook and YouTube directly into the home page. The new site also features a mobile friendly layout for use on the go.

I’ve yet to try their apple pie offering, as I usually just stick to coffee – and damn fine coffee it is.
So to those of you that have tried it, what do you think? Do they use macintosh apples? Granny Smith? Gala? Red Delicious? If you think you know, tweet at them, because you may just win something for free.
