I've been seeing ping.fm showing up as a source of tweets on Twitter. I've tried lots of little desktop clients like twitterific and twhirl and like them all more or less. When I started seeing ping.fm on Twitter, I popped over to the site and saw that it was a Web based service that you needed an invitation to use the beta. I sent out a little tweet asking if anybody had a beta code. My friend Walkah quickly sent me the invitation code and I signed up rather quickly on my iPhone.

Ping.fm is cool because it aggregates all your favourite social networking sites. I immediately set up Twitter, Plurk, and Pownce. They were a snap to setup.

1) Click on "Not Setup"
2) Put in your Username and Password for the service

NOTE, I am not responsible if you use this service and something goes wrong. You are putting your username and password into a third party application.

Once you have your services set up, a single post will filter to all of the sites when you make a post.

Facebook is a bit more complicated--you'll need to use your "Application Key"--but if you follow the instructions provided by the application, you shouldn't have too much trouble setting it up as well.

One minor nit, you can post to all your social networking micro-blogging sites, but you can't see the stream of folks that you follow through the service. This means you need to follow each of your streams individually.

All in all, I think that ping.fm is pretty cool and worth taking a look at. If you regularly update a bunch of services with the same or similar posts, this will save you a lot of effort.

Let me know if you need a invitation code. I'd be happy to share.
