Google now allows Blogger.com users to use their Google+ profile on their blog. The feature was until now available to Blogger in Draft users. Also, Google has started rolling out the other Google+ features:
First, starting today, if you have linked your blog to your Google+ account you will be presented with a prefilled Google+ share box immediately after publishing a post. The share box will contain a +snippet of your post that you can share with your circles on Google+, infomrs Bruce Polderman, Product Manager.
Of course, you can "disable this sharing prompt at any time on the "Settings - Posts and Comments" page. And you can always share individual posts on Google+ by selecting "share" underneath the entry in your post list," says Polderman.
You can start using the new Share to Google+ immediately if you've already chosen to use your Google+ profile on your blog. If you haven't yet made the switch, visit here to get started.
"What happens when I switch to a Google+ profile?
Information on your blog previously based on your Blogger profile, such as your display name and your photo, will reflect the information from your Google+ profile.
In places where your display name appears, your name on Google+ profile will begin to appear once you've made the switch. However, any comments you've made before the switch will continue to show your Blogger display name. All instances of your name on feeds, your Blogger profile gadget, new comments, and instances of your Blogger display name on past comments will link to your Google+ Profile.
How will I control my Google+ profile privacy settings?
You control your profile privacy settings and make all edits through Google+, and its settings will override any profile preferences made in Blogger before switching.
Although you can set various privacy settings for specific fields of information, your real name and photo (should you choose to upload one) will be publicly available on Google+. If you blog under a pseudonym and do not want your blog to be associated with your real name, you should not migrate from a Blogger profile to a Google+ profile," explains Google.
