I am on the +.  I thought the linking of other accounts was not very intuitive, but the rest of the features perform well.  Since it is a beta, I am assuming it will be tech heavy until they open it to the masses.  It looks like they are integrating + pretty well with iGoogle and the other customizable apps in the Google toolbox.  I see my old profile was overwritten with my + info.  I will continue to use it and see how I can grow my friends.  The circles idea was one that was developed back in the early 2000 by a company called My Circles.  I was involved in that project.  Circles are very difficult to manage, but not as difficult as privacy settings in Facebook.

I don't have invites or you interested folks would all be invited.  

Barrett and about 300 robots that follow me on twitter know that I share a lot and it is all over the place, professional stuff, Duluthophile (#dlh) stuff, and more, mainly lots and lots of inane comments about my family and kids and crappy snapshots with a cell phone cam.  Same for Facebook.  So I love the promise of circles.  I'm wondering if Frank could share more about why it is hard to do?

Facebook does allow you to block updates from various apps (which is nice if you want to see that so-and-so posted hillarious drunken photos of themselves, but could give a rat's ass that they are now a 12th level mobster in Mafia Wars). Just blocking all the game-app comments cut my facebook feed by 60%.

Interesting, Barrett.  I was just thinking MySpace is looking kind of clean and tame compared to the evolution of Facebook.  I also have blocked most game apps from notifying me on facebook although a few occasionally sneak through.  I think games may be an evolutionary stage of social media, though.  As in, when I started on FB I played games but I don't anymore.  Many casual and new usuers seem to really enjoy the games but once you realize that they don't really do much and the whole point is to get people to sit online and view ads.  Not long after the demise of Scrabulous I realiized that social media games were all played out for me, pardon the pun.

share!

I was recently invited and accepted to join. 

Before creating anything beyond the initial account (not adding anything - note: as you do enter info, there is a 'web' button which you can click to allow/disallow permissions of each section to web, circles, extended circles, me only, etc. and more in various places as well - some areas did not have the option and will be shared regardless, such as the name/ID you use), I decided to do a little reading and came upon a pretty all encompassing review under the "Reader" tab of Google's new menu bar done by a techie on his/her own blog and fed to Google's recent feeds about Google+ and what people who are using it think about the review, and more in the comments too.

The Reader is kind of fun, and addresses everything from funny icanhaz sorts of pics created (mainly taking the piss out of facebook and other social networking sites), to actual reports, and other questions, or reviews, entertainment items, and more. 

I clicked this link to read the review from the originating blogsite and noticed it had also been updated in regards to the TOS for Picasa (Google+ uses Picasa as the photo interface). 

Anyway, for those of you who don't have yet, and want to know more, this overview/comparison helped me to see some differences - especially since I am not at all a facef*ck or twithead fan - by choice - due to all it's issues, limits, lack of certain features, dislike of how messy it looks, and permissions reasons.

Anyway, hope this helps those who are seeking more info, or wondering where to find their invites. 

Whether or not it'll be worth my time or anyone else's remains to be seen. As some have mentioned, it gets old creating profiles and loading all your stuff only for some new shiny to come along and do it all again, making one question if it's really worth it to be spending so much time online vs off in real social settings, yadda yadda. (At least for me until the weather turns crap.)

Also, once you accept your account, you can invite others - there was no waiting period, once I had located the invite link (Go to your homepage, then scroll down, and you'll find the invite icon is the last in the list in the right-hand column.), I sent one to another of my Gmail accounts to test.

The review says it's limited to those with Gmail accounts, whether that's still true or not, I don't know as I didn't bother to send to a non-gmail acct as of yet, but even if you have to make a Gmail just to try it out, no biggie, unless of course you hate Google and Gmail, as some do. 
To each their own.

Cheers!

Came across a more detailed explanation on LifeHacker of the pluses/minuses/how to control privacy and information in google+ which may be of interest to those of you looking for more specifics.

Cheers!
