I think I wasn't clear enough there. Google+ is not more widely used than twitter NOW. There are a lot of people on Facebook who were formerly on Orkut, Myspace etc who've never had a twitter account and just don't GET twitter. If I had to pick the next facebook sized network, it would be Google+ and not twitter for that reason.
PS: I don't even believe the current growth/engagement numbers coming out of twitter entirely. There's a lot more spammy accounts there than used to be that put out hundreds of tweets a day and I wonder if that's heavily padding twitter's user growth currently. Most of my current followers are "fake". Same with my friends who aren't particularly famous. The statistics don't reflect this properly.
