Just wanted to flag up an article I wrote recently for Business Computing World on the business potential of Google+.
The short version: it’s still too early to say, especially since Google hasn’t unvieled the brand pages yet, so any conversations about the platform’s potential are a little premature. Nevertheless, it’s a nice service and Google has built up a lot of valuable experience with its advertising platform and analytics tools, so it’s safe to assume that will be deployed with great effect on Google+. Eventually.
