Dodgeball.com is in the Mobile Social Software (MoSoSo) space. This seems useful and easy to use. It is within Google’s stable of applications, so it recognized my Google account and asked permission to use that account and log me right in. There certainly need to be clean ways to mix mobile voice telephony with the Web. This mix, of mobile phone, Web, and community can bypass existing niche players. One comment is that this application, unlike many attempts at user-generated content, rewards users (with utility) for creating online content. In this case, a listing of personal venues with comments solicited from all users. Nice.
Note in 2018: Well, Google let Dodgeball languish. In case you were not aware, Dodgeball’s founders then created Foursquare and Swarm, which I continue to use into 2018.
