Here are some tips for using Google Plus for business.
Google Hangouts on Air are now available to everyone. This means you can easily record a tutorial, an interview, or a demonstration, send it to Youtube, and add it to your channel. You don’t need any special equipment or software, just a webcam and your computer.
Here’s how to do it:

Sadly, there’s no way (yet) to publish to Google+ automatically from your blog or from other networks. However, you can do it the other way around. Here’s how tech writer Mike Elgan does it: Publishing from Google+ to Twitter and Facebook

It’s a great way to get extra visibility (and credibility). If you haven’t connected the two yet. Here’s how (straight from Google): Set up your author tag. It looks a bit techy, but it’s mostly copying and pasting.
Update: You can, I just discovered, use a Chrome browser extension to write Google+ posts and schedule them. It’s called DoShare, and you can get it here. Thanks to +Ivan Dimitrijevi for pointing this out.
