"Everything is smoothly integrated into one place, from Google Chat to the notification center in the upper right. I wonder if I will be able to access my gmail and iGoogle widgets from Google+? If so, then it could provide a one-stop-shop for everything and take over as my browser homepage (something Facebook never had a chance at doing). One thing I have to be thankful for in that Google+ works well internationally because it remembers my Google settings. No other company could manage this.
Overall, like any social network, the #1 determining factor will be adoption. If my friends use it, I will use it. But adoption is based upon a good user experience and a service that solves a problem, and to my surprise Google+ seems to be accomplishing just that (I actually did not expect to like it). "
