Review so far.
- Very basic look, feel & functionality
- By 'basic' I don't necessarily mean easy to use, there is a small learning curve
- Very limited one-to-one connectivity. You need to tag people in a post, or email. There is no 'wall'
- I like the +1 more than the FB 'like', will be interesting to see how it integrates my overall google experience with search indexing and whatnot
- Circles are great
- Limited release is annoying. Hard to network socially without a real network
- Hangouts look interesting, but haven't had a chance to use it... I assume it's just a group Skype buzz
- Sparks a a little pointless, but will no doubt get better with more +1ing
- Needs 'events' functionality that integrates with my google calendar and I'll be a happy chap
- Notifications are fucken awesome, and come up in gmail/RSS/calendar windows also
I still really enjoy Facebook and get a lot of use out of it, so won't be running away in a hurry. For me the enjoyment of Buzz, which should now translate to Plus, was that I had a smaller, more manageable network of people who were more like-minded in terms of the things they share.
Overall, a good start that will need a fair bit of fleshing out to really compete with Facebook. But hey we all knew that.
