As I wrote in a previous post, in its present incarnation, it is not designed for business pages (but they are coming). Instead of thinking that this means it is not a place to take your brand, read what Chris Brogan has to say on the subject:
It’s funny how many people are lamenting the temporary shutdown of brands on Google+. Meanwhile, I’m seeing lots of smart business people connecting with people, making relationships, sharing a mix of personal and business materials, and building relationships that will transcend the vagueness of following an official stream.
Business is about humans connecting with humans. This new platform is the top shelf of potential for doing a great job of doing that. Keep doing what you’re doing as a brand of one, and just be sure your ABOUT page represents your organization well.
Great advice for non-profits! So in the words of Chris again:
Go forth. Be the brand. Just be you as the brand!
