I have +1'ed few sites, and they are showing in my Google+ profile to my "extended circles" (people in my circles and their circles). However, can I make my plus-ones public? The same way that I can share a link in my profile, and it is visible to everyone, even not logged-in users.
- Visit the +1 tab on your profile
- Click on the big blue Edit button at the top of the page.
- Check the Show this tab on your profile checkbox
- Click on the blue Save button below that.
+1's will now show on your profile to all users, logged in or not.
