Foursquare recently released a fun yet very interesting infographic that described the state of the foursquare-sphere for 2010. the graphic reveals the who what where when why and how of foursquare and tallies up the numbers from 2010.
Like social media in general, businesses are still trying to figure out why social media, why foursquare and how to capitalize on it and leverage the apps and services into $$. From my perspective, business owners, at the very least, need to take over ownership of their information and listings and providing accurate information about their business to the users. Foursquare (and other social apps) offer tools and analytics to business owners and these need to be used.
Check out the stats, some of the main uses and users of foursquare, and a look at what businesses can do to take a advantage of this social service.
