How to Sync Your MySpace and Facebook Status Using Twitter
If you've got multiple social media accounts, such as MySpace and Facebook, it might be hard to keep every account synchronized and up-to-date when it comes to your status (and let's face it, you'll just feel all out of sorts if everything isn't up-to-date). There's no magic button that will update both MySpace and Facebook at the same time, but you can update them all by using an intermediary service: Twitter.
If you haven't already signed up for a Twitter account, get one.
On your MySpace account, install TwitterSync.
On your Facebook account, install an app like Tweeter.
Update your status on MySpace and sync it to Twitter.
Your status updates on Twitter, which then brings it to Facebook. Instant harmony.
Obviously, a Twitter account is much more than just a bridge between two competitors, but it's helpful here for just that purpose.
