The caption from the YouTube video above says it all:
With Direct Connect, you can automatically add Google+ pages to your circles from Google Search. Just add + in front of the page you’re searching for.
The combination of Google+, +1 buttons on websites, in Google search results, Google ads and more, and the addition of Google+ pages for Small Business, Social Media has a new powerhouse. If you are unaware of what Google+ is, haven’t yet created a Facebook Page, or you want more profit for your Small Business, now is the time to create a Google+ profile and get familiar with the Google+ pages that major brands like Pepsi and others launched yesterday. Google gives EVERY business, brand, band and beyond to the power to create a Google+ Page. We create the W3 Consulting’s Google+ page late last evening; feel free to add us to one of your Circles! And, see you on Google+!
