Google+ has the same buzz and expectation which was associated with gmail when it was first launched (with respect to scarcity of invites). I am based in India (not sure how location matters) and I remember I had to wait a few weeks for someone to invite me to gmail.

If that is some indication, then Google+ looks to be a winner. (I remember how I moved from Yahoo! and Hotmail email to gmail after I finally got the invite).

It has the same buzz and expectation as Google Wave too. I can control my anticipation.

Yeah, but unlike Google Wave, you don't really have to explain it to people. "It's like Facebook without all the Farmville crap" seems to suffice for even the least techie of people (as long as they are already on Facebook).
