Last night, Facebook announced the launch of Facebook Places at their headquarters in Palo Alto, California.  Facebook Places is a location-based check-in service that allows users to share where they are, find out where their friends are and discover places in their area. Users can also tag friends when they check in, something that other services do not currently offer. The service allows businesses to create or claim Places on Facebook and encourage users to check in. Eventually this could lead to the ability to offer discounts or promotional messages to users at a location or nearby.

Location based check-in services have been growing in popularity and it’s been hard to ignore the rumors and hype surrounding the launch of Facebook’s own product. The big question has been: will a Facebook check-in service destroy competitor applications?

During the announcement, Zuckerburg joked about all the features Facebook would not be integrating into the new platform.  However in a dazzling display of netizenship, Facebook decided to play nice with Foursquare, Gowalla, Yelp and Booya (the makers of MyTown). While Facebook will continue to port over all your social good from the most popular location-based services, the impact on these competitors remains to be seen. According to the most recent Mashable poll, only 30% of people say they will use the service (but another 30% responded “Maybe: I’m going to wait and see”), suggesting adoption may start off slow.

Much like Social Graph, Places promises to unify even more data from across the web. It is only a matter of time before Facebook launches other services such as: peer to peer payment systems, similar to Paypal, group deal sites, similar to Groupon, and online classifieds, similar to Craigslist.

According to comScore, as of July Facebook is the third largest video site in the U.S. Last March the Private Data Equity Center valued Facebook at $35 Billion. InsideFacebook.com states they are projected to hit $1.1 Billion in ad sales revenue after hitting 700 million in 2009. With these numbers, we’re not to far away from saying, “Hey I’ll just Facebook you the money,” or “Just sell it on Facebook.”

At the Mashable Media Summit yesterday, Adam Ostrow of Mashable interviewed Dennis Crowley, founder of Foursquare, who got the crowd excited about his company’s plans.

This year, the company raised capital, hired 25 people and made some money. Still, Foursquare has yet to make any profit because, as Crowley explained, being profitable is not a focus right now. Instead the team is focused on innovating new features and building an infrastructure to support their impressive growth.

According to Crowley, the Foursquare team has so many ideas they ran out of whiteboards at the office. For users, this may mean more badges, city travel guides based on your friends’ favorite places, more “to-do” features, the ability to connect with people at your location, retail rewards for check-ins and maybe even another title to strive for in addition to Mayor. For businesses, this may mean more partnership opportunities, more input on badge creation, greater access to customer data and the ability to design rewards for check-ins or mayors.

When asked about Foursquare haters (Time magazine labeled Foursquare among the 50 worst inventions), Crowley politely countered with the notion that people like software challenging you to do something, inspiring you to do it and rewarding you when you achieve it.

It’s been a few weeks since Microsoft announced that Bing would start integrating Foursquare into Bing Maps. Avid Foursquare users know that sharing and consuming location-based data with your friends can be a helpful, if not fun, way to explore cities. When Microsoft announced the new integration, we immediately wondered if this meant that users would be more apt to use Bing Maps and if there was an advertising opportunity for local businesses. The Razorfish search team weighed in and the response is pretty split as to whether this integration will prove beneficial to Microsoft and local businesses (although more are optimistic).
