Playing with Ping.fm
Now that Ping.fm is out of private beta, anyone can sign up for an account. The purpose of Ping.fm is to update all your social networks in one shot. So if you have accounts with Twitter, Facebook, Plurk, Pownce, MySpace, Tumblr, FriendFeed, Jaiku, Rejaw, Delicious, and more, Ping.fm can update these services all at once.
Looks like you can even update your social network status using an iPhone optimized Ping.fm “app” or even through IM with GoogleTalk.
