Best Practice in our opinion is a Bold Title (Easy on the CAPS) and a 5/6 line paragraph, with a Read More link underneath. You can also add a couple of #hashtags . The bold title is to catch attention, while restricting your copy to 5/6 lines prevents it from being collapsed. Add Italics to emphasize certain phrases, or to quote from a linked article. Follow this and your posts will look better and be generally more "shareable". Add a Photo, or Link Snippet to finish.
