I clicked on the link, and am now likely going to count as an active user because I was logged into gmail. In other words, I am NOT a g+ user, but google probably counts me as one because of my gmail account. So, scottbartell may have a valid point.

You clicked the link to plus.Google.com, meaning you just acively used the site. Are you suggesting that referrals should not be counted as active uses?

Now, Direct visits would be interesting to get some counts for.

It's a pretty meaningless measure - that's all I'm saying.
