Every social media venue has it's own language and style of posts. Some are hashtag laden, some prefer warmer stories, and some are all business. You wouldn't wear the same outfit to a wedding, a business conference, a BBQ and a cocktail party - or would you? If you think one look covers it all, you may want to stop reading. If you only think you need to change shoes, stop reading.
Let's first cover the posting, not commenting styles for these venues that are often or exclusively used for business.
Include a LINK to something, unless you are sure that the inspiring quote you are posting is a standalone. But you have my attention for that VERY brief second or two - make it count.
Find the company or people you are referring to and @mention them to give them an alert that someone is talking about them.
