I seen only good things for google+ in the future
It brings the social interaction from twitter in a far more user friendly facebook style shell
Facebook has always been limited in that it must be a mutual friendship to receive content from other users. So, for example, if I send Kevin Rose a friend request on facebook, he might not accept it because he doesn't want to receive my updates.
Google+ works more like how twitter works, but twitters biggest fault (IMO) is it's terrible user interface. If you are following a lot of people, content comes in to fast to keep up.
Also, keep in mind it's just the start now. There are loads of features that will most likely be added going forward, the one I'm looking forward to the most is the business pages. It will be interesting to see how google implements it.
I'm very excited about the whole thing, and am willing to bet that google+ will be bigger than facebook within 2 years
