About 60-70% of the tech news yesterday was flooded with reports on Google+, it's actually amazing if any of us mere mortals made it in at all. The major players were all brought in to ensure that they could report back on what is being done, and I have to admit... for somebody who strongly dislikes Facebook, it looks pretty interesting.
The one thing that everybody needs to keep in mind when comparing the two is that Facebook has been around for just over 7 years now. They've had a long time to build, adapt and learn (and in some cases, ignore). Google+ can build on that experience, yes; but they're still brand new fresh out of the nursery.
