Just started using it. Not sure how I feel about this.
My 2nd round invite came through just as they were deciding it was “over capacity” (although I’m pretty sure people who got theirs minutes before me got in), but what really amazes me about this whole beta invite thing is that AFTER 29 YEARS OF USING THE INTERNET [not a typo] somebody/something (in this case, G+) can still make me feel like I’m not nerdy enough.
