Ezra Klein sees it as a better Twitter:
[I]t turns out that Google+ retains Twitter’s appreciation of asymmetrical social networks: people can follow you without you following them, and you can choose to broadcast messages to them, and they can reply, and so on. I’ve been experimenting with this over the last few days and have been really surprised and impressed by how rich the resulting discussions are. It’s really highlighted the drawbacks of the 140-character limit and made Twitter a lot less appealing to me.
Steve Kahl thinks this asymmetric use of Google+ will make it appealing for both families and business.
