If you’re looking for a great tool to link all of your social sites together to create a single point of date entry that multiplies across the internet, Ping.fm is pretty close to perfect.
I’m using it to post to my Typepad blog in addition to posting to my Ning blog and MySpace blog all at the same time.
My Twitter profile will update automatically once the blog post is fed via Twitterfeed. This will also result in updates to my status on Facebook and FriendFeed.
I may need to change some other accounts, like Tumblr, so that they are updated directly from Ping.fm thus eliminating what is currently an extra independent step.
Once Ping.fm is set up to allow for updating across several Ning networks, I will have achieved true nirvana.
