Having to update Twitter, Facebook, Google Plus, Plurk (Seriously WTF is Plurk!?!) separately can be a pain. Publish Sync for Chrome looks to fix that.Publish Sync is a Chrome extension that will publish to multiple networks at once. The nice thing about this one is it will let you choose which networks you want to publish to, down to the specific Circles when it comes to Google Plus’ case.
I should point out that some people have complained that this extension has published spam posts to their services when they did not want them to. I haven’t had this happen yet, but it might be a possible risk to people. It’s one I’m willing to take if it means I don’t have to post on 5 different sites.
You can find Publish Sync at the Google Store
