The service, currently available for Mac OS X clients, with a Windows version planned to debut soon, scans your iTunes library for installed applications, presents them on the Web in a faux iPhone interface, and encourages you to share your library with friends by way of social networks, including Twitter and Facebook.
The service is in closed alpha now, but we have 50 invites available, first come, first serve to Mac OS X users. http://bit.ly/appsfireLG
You can see some example Appsfire libraries here:
- Ouriel Ohayon's Appsfire: http://bit.ly/ourieltopapps
- Louis Gray's Appsfire: bit.ly/lgiphoneapps
Also part of Appsfire? A new link shortener for iPhone developers and bloggers, who all know the usual links to the iTunes Store are a complete pain. You can find that here.
An intro to the service can also be found on YouTube.
