I have integrated Google+ with Blogger, which is great! Except for a couple of minor annoyances. The first is that the “About Me” section changed to my Google+ profile. But I had preemptively copied the HTML from the original “About Me” block and pasted it into a new widget. The link still goes to my Google+ Profile instead of my Blogger profile, but I can live with that (or create an actual “About” page and send it there instead).
Another issue I have is that I prefer to show my handle to users instead of my real name, though I don’t mind my real name being known. A quick Google search led me to several solutions, many of them editing the HTML of the template. But I also found instructions for using CSS to change the author name on posts to a nickname. As noted on that site, it’s only really useful for single-author blogs, but it serves my needs just fine for now.
