Plus mentioning people on Google Plus is a way of connecting your posts with your friends or other influential people. This is easy to do directly on the Google+ platform, however it’s not so straight forward when copy/pasting from a document.
Many people compose longer form posts on G+, which is one of its great features, but they are easier to compose in a document program like Google Drive. The problem here is that when you copy/paste out of Drive you lose all your +mentions.
In this tutorial Michael Bennett shows you how to compose in these external document programs and maintain all those +mentions! This works the other way as well. If you wish to copy/paste the contents of a post with a lot of +mentions you can maintain those links by following this tutorial.
In this tutorial Stephan Hovnanian takes this idea, and shows us how to use these techniques with 3rd party social scheduling programs. These two tutorials will really help you get the most out of the time you spend composing posts on Google Plus.
