New to Google+: Pin a Google+ post to the top of your profile or page
Today Dennis Troper Announced on Google+ you can pin your posts to the top of your stream.
People often have posts that they want to make sure get seen when someone visits their profile, like a great nature shot from a recent family trip. Businesses also have content they want to highlight such as photos of a new product or a trailer for an upcoming movie.
So if you want people to see a specific post first, you can pin that post and even if it is weeks old, it will remain at the top of your profile.
To pin a post, open the drop down menu on any public post when viewing the posts tab of your profile or page on a desktop browser. Desktop and Android users will see your pinned posts, with iOS support coming soon.
