We have seen more and more new kinds of WordPress themes lately, as original as the imagination of the developers was. But for a few months, and with the development of services like Foursquare and Facebook places, teams like Woothemes and now Templatic have starting working on geolocation-based WordPress themes.
And today comes a new theme from Templatic, grouping lots of geographic location features: Geo Places
Geoplaces allows you to integrate maps, user reviews, contact info for places, and nearby locations. In my opinion, we have got another proof of how powerful WordPress can be if used properly!
