Share to G+ Bookmarklet Makes it Easy to Share Links on Google Plus
It is easy to click on the +1 button now found on nearly every Google search result, but if you want to share a link with one or more of your circles on Google Plus you've had to manually copy and paste the link. Share to G+ is a bookmarklet that allows you create a post in Google Plus linking to the web page you're currently visiting by clicking on the "Share to G+" button in your bookmark bar.
By default the post will be published publicly on Google Plus, but you can change that by clicking on the edit button and choosing streams. You also have the option of adding a location to your post.
Opening up Google Plus and copying and pasting your link into a new post doesn't take a lot of time, but if you like to share items with your streams frequently you'll save time by using Share to G+. Since bookmarklets are just one-click tools to manipulate data you don't have to install anything to use Share to G+.
