I have an old blogger account and was being prompted to switch to using g+. The prompt said that I could do a trial run and I decided to switch. However, after switching to my real name, I couldn't find a link to switch back to my blogger username. Luckily somebody had blogged about it and found a link to switch back. The change would have been permanent after 30(?) days.

I wonder how many bloggers have their real names and pics appear alongside their blog posts in google search because of this.
