Few days ago aakar also had similar arguments about why google is biased in peculiar way to names.
This week, I also witnessed GrrlScientist's G+ profile being snatched and suspended...and her rants in twitter.
If you have a pet name in blog-o-sphere, forget about getting into G+ circle: Not cool!
Stay in facebook, or twitter or whatever.
I can hear the other side: if you want to remain anonymous... why on earth do you need profile?
I do not know.
One day google will claim that all the blogger profiles should be merged to G+ profile. Then there will be a lot more friction.
