DC tip: Improving the teaser for your post
When posts are displayed on the DC homepage they only show the first part of each post. This part is known as the teaser, or the trimmed version. The DC software does its best, but without being given any hint by you it can sometimes produce teasers that are of limited value, e.g. "Hi!"
