Ping.fm is a new service that allows you to update all your micro blogs at once. Ping.fm currently supports Twitter, Jaiku, Pownce, Facebook and Tumblr. You can post messages using Web interface, email, IM and iGoogle gadget.
Ping.fm is simple service to send messages to micro blogs, when you send a message using ping.fm it will be posted to all the supported services provided you have setup all the accounts. If you want to send messages to only specific sites like Twitter you can use “triggers”
@fb message – Post directly to Facebook
@jk message – Post directly to Jaiku
@pn message – Post directly to Pownce
@tr message – Post directly to Tumblr
@tt message – Post directly to Twitter
For posting to Facebook you need to install Facebook application first. You can also post text messages from your phone if you can send email from your phone.
It is a nice service but how far it is useful for you. I am not giving up Twhirl for this, because twhirl allows me to track twitter conversations along with posting. With Ping.fm sometimes you have to wait a few minutes before your message shows up. HelloTXT is a similar service that allows you to update all micro blogs at once.
