earfl is like Twitter for phone calls. Instead of sending in an SMS update, you can just dial a number and say a little something. The recording will be linked to your account on the Web, and can then be shared with family and friends. Attach an image if you'd like--this makes audio recordings (especially those from the phone) more interesting.
Stories can be rated, commented upon, emailed out to friends, or embedded into other social networking profiles or websites. earfl also features groups, so you can connect with others regarding a particular topic of interest. Another useful feature is the ability to send a recording to another user and invite them to participate. For this option, earfl will actually grant them a redemption code that allows them to submit a recording without having to set up an account.
Each public story has a ShareThis button, so items can easily be spread to most major social media networks and bookmarking sites. And while ShareThis allows these stories to be sent to other microblogging tools like Twitter, an automated option for users would be helpful as well, especially if they're looking to diversify their content for redistribution purposes.
