Who's using Google Plus for marketing?

I'm really interested to know how many of you are actually using Google+ as a marketing tool.

I've noticed the number of business pages rising. It's no doubt that Google+ is on the move but is it actually seeing a lot of attention of business owners? From my personal experience, I have to say yes. But it's not the influx of new members that I see flooding through the gates.

For the most part, I see users that had a personal page open up a business page once it was made available. So most of it has been somewhat internal since the latest jump in popularity. Remember they hit over 10 million users in less than a month.

The traffic influx has now flattened out. There is still a mega load of activity on Google+, increasing daily. My though however is what is preventing owners not currently using Google+ from jumping aboard?

Is it because they are simply not aware of it's powerful tool set? Is it because they are scared of change? I think maybe people aren't really connecting the dots when it comes to Google.

We think search and email, and not social. But now, social has been integrated into many Google products and list is ever growing. Here's a couple of questions for you?

1. Do you have a business page? If so, have you found any success?

2. Do you think that Google+ will become a very popular marketing platform?
