Everbadge is a mobile social network with loads of free goodies for Android users. It's also a place where Android developers can effectively promote & grow a fan base for their app(s) absolutely for free. Source : everbadge.com
Move over Foursquare, Gowalla, and GetGlue. Here comes Everbadge, a social network aimed at users and developers for the "Green Machine" Android. It has everything you would expect from a social network app/site. You can create a profile, upload your pic, earn badges, post status updates, etc. To date the site has 97,000 members (make that 97,001 since I just signed up 5 mins ago). What seems cool about this is that if you're a developer showcasing a new app you can get feedback here from fellow Android users. They also offer wallpapers to download and a few games/apps. It's going to be cool to see how far this goes.
