Google+ Communities just launched, providing a way for anyone to create a discussion group or forum, as part of Google+. Unfortunately, one of the biggest challenges that the service faces is how some people are hyping it. Let me get a few things out of the way.
Google+ Communities does not change anything. Things are exactly the same today as they were the day before the functionality launched. Google+ Communities is not anything new, except within the world of Google+. Google+ Communities does not, will not kill anything, whether a specific branded platform (like Facebook) or a type of platform (like forums).
