I have managed to get into the Google Plus beta, and I have invitations available RIGHT NOW! I am building a NASCAR circle, and it's growing like a weed, so if you want in early to get the hang of it, post an email address I can send an invite to, and get in. Google Plus is the best parts of Facebook and Twitter, along with all of the cool Google tools integrated into one really killer social network. There are so many cool tools like Hangouts, where you can start chat groups with friends in your circles, sparks for any interest you can imagine, it goes on and on. Again, post an email i can shoot an invite to here, I'll get one to you, and create a circle (I made a NASCAR circle to go along with the pre-named ones for friends, co workers, etc)...
I've created my Nascar circle and added you anyone else on the group can add me to their friends circle if you like
all current members just got an invite all at once-go check the email accounts you use to login to NN with, be sure to look in spam too, sometimes they go there, esp. Yahoo email. after you are in (and hurry before google turns them off rendering the invite invalid), go to http://davenorrisplus.com (my G+ page) add me to a NASCAR circle!
