One of the first complaints I had about Google+ was that it meant having to manually input items multiple times as Google+ was isolated from the other social sites. Facebook and Twitter, despite competing in the same general social space, played nice and allowed one to easily sync their accounts: you update in Twitter, it can can automatically update your Facebook page (and vice-versa).
But with Google+, that isn't the case.
They do give you the option to "share" on Facebook and Twitter, which most of time would be enough.
But if you're anything like me, you might not want that manual effort each time and instead want it done automatically.
Luckily, there are some ways to make your life easier, freeing you from having to copy/paste across multiple platforms.
Here's a system I put together that seems to do the trick, taking my posts on Google+ and automatically updating Facebook and Twitter.
Give it a read, try it out and let me know if it suits you.
