You've been on Google+ for a few weeks now. You're loving it. You're exchanging thoughtful posts, pictures with your friends, meeting new people and following lots of interesting, intelligent people. There's just one problem.
You're still stuck in Facebook and/or Twitter because not everyone has gotten the memo that Google+ is the future. You find yourself dreading having to log into Facebook and Twitter in addition to Google+, but you still want to keep up with all your friends and family.
Short of forcing everyone to move, you can have your cake and eat it, too. While the Google+ API is not available yet for developers to play around with, and create simple cross-posting tools, you can sync your social networking posts on Google+ with other places using a few different workarounds.
Install Google+ Chrome Extensions
There are some great Google+ Chrome extensions that will let you cross-post to Facebook, Twitter, and other social network streams.
The most useful one I found is Start G+. In addition to sharing your posts to Facebook and Twitter, you can also view your Facebook and Twitter streams inside your Google+ stream. This way, you never have to log back into Facebook or Twitter again, and you can keep up with all of your major social networks.
Other Google+ Chrome extensions let you cross-post by adding a small button to each of your posts, so when you compose a post, you can click on a Facebook or Twitter button. Share+ supports Identi.ca, Ping.fm, Reddit, FriendFeed, Tumblr, Posterous, MySpace, Delicious, Wordpress. ExtendedShare supports Twitter, LinkedIn, Facebook, Tumblr, and Identi.ca. G+Tweet, Google+Tweet and ManageFlitter all let you share your posts directly to Twitter.
Post to Your Blog
If you’re the type to write long essays in your Google+ posts, you may be interested in cross-posting them to your blog. Fortunately, doing this is pretty simple. Just create an RSS feed of your public Google+ posts using PlusFeed.
All you have to do is grab your Google profile user ID number, which is the long string of numbers after https://plus.google.com, and add it to the PlusFeed URL: http://plusfeed.appspot.com. If you have a WordPress account, use the Lifestream plug-in, and add your feed to the Generic feed settings. Then your posts will now show up in WordPress.
