This is a workflow based on the "Search and Share on Google+" workflow by the user Chris on this forum.
The only flaw in this workflow is that it doesn't grab the URL from the browser automaticly, with this update/workflow it will.
To share a URL to Google+ with this workflow, you do the following:
Use the keyword 'gplus' and select 'Share a link on Google+' (or setup a keyboard shortcut) to activate the sharing of the URL from the frontmost tab in your browser.
If you'd like to add a comment - write it after a space between the gplus keyword and the comment you would like to write.
Supported Browsers:
Google Chrome
Safari
Firefox
Opera
Creds go to Chris for this one!
