Saturday is Foursquare day, and Badgy is partnerting with @4sqATL to offer a very special Atlanta Foursquare Day 2011 Badge.

Folllow @4sqlATL on Twitter to find out how to unlock this limited edition Badgy badge when it is released.

You might wonder why fans should talk about Foursquare outside of that eco-system, and there are a number of good reasons that apply just as much to the companies we work with every day as they do to Foursquare.

• Huge Audience - not everybody knows about Foursquare, and not everyone who knows about Foursquare uses it. As people share their enthusiams for Foursquare on "Foursquare Day", it's an opportunity to recruit new people to use Foursquare as they see the enthusiasm across their Twitter and Facebook streams. Facebook is bigger than Twitter is bigger than Foursquare and most companies' web sites. Social campaigns help people discover how to engage with ideas, content, and products they already love or would love if they knew about them.
• Access - Foursquare is a pretty closed system - you can't create your own badge. If you partner with them at a VERY high level like Bravo or CNN, you can have some badges, but this level of partnership is only within reach for the very largest companies, and even then, location-based check-ins don't necessarily make sense for their brand, which brings us to:
• Non-location - Foursquare isn't a place. Atlanta is not a "place" on FourSquare, though it is a collection of places. Foursquare's solution for non-places is usually to either ask you to "shout" something with your check-in, or designate a few special places unaffiliated with the brand where you check in to earn the badge. Many companies we talk to aren't a "place", and Badgy can help by letting users "check in" by engaging with them on the much larger social networks they are already using - Facebook and Twitter.

We hope you'll enjoy Foursquare day as much as we will enjoy celebrating with you. Again, keep your eye on @4sqATL for details on how to earn your Atlanta Foursquare Day 2011 badge!
