GoWalla About to Pass the 100,000 User Mark

. gowalla1.jpegGowalla, a location-based social application developed by Austin, TX-based Alamofire is about to pass 100,000 users, according to some of my sources. The company is going to hit the milestone over the weekend, having just crossed 99,000 users. Gowalla recently raised $8.4 million in venture funding from an assortment of investors including angel investors Chris Sacca and Jason Calacanis.

In comparison, Foursquare, my favorite mobile app, is closing in on 300,000 users having just crossed 290,000 users. Foursquare earlier this week released the Blackberry version of their service. Gowalla and Foursquare are vying for user attention at the same time competing with local search web service Yelp has started to encroach on their turf with its new mobile application. If you get a chance, watch my interview with Josh Williams, CEO of Alamofire to get his thoughts on location-based services, Twitter, Yelp and his competitors.
