I’ve been using Ping.fm for a few months now and have found it extremely useful for updating my status on multiple social networks at the same time.  I use it to update the Wizkid Sound profiles we’ve set up, including MySpace, Facebook, LinkedIn, Twitter, and Plurk.

There are several ways to submit updates using Ping.fm: via IM (several services), through the web interface, by email, and others.  I update using the email option from my iPhone because I don’t have to worry about my internet connection…the email will get sent as soon as there’s connectivity, and my updates will get processed.

The development team (Sean?) is very active…it seems that every week there’s a new service to ping (that I just have to sign up for) or new features, like automatic link shortening, the ability to send updates to a specific set of services, and also the ability to post to blogs.

Send me a message if you’d like an invite as Ping.fm is currently in private beta.
