Google Plus is all about the sub groups
MySpace Tom (he used to be my friend) looks at Google+, with a nod towards Facebook and Twitter, to try and work out who Google are targeting and what will be used to grow the network:
G+ doesn’t need you to have a critical mass of your friends or users in a certain area to be interesting (that’s Color’s problem)… Because G+ is a potential “Facebook replacement” that also has a Twitter side, G+ will continue to grow & grow and as a critical mass of your friends start using it, you’ll then be able to use it in a more Facebook-y fashion. Put another way, G+ basically is a combination of Facebook & Twitter.
