LinkedIn is a social networking website for professionals. Unlike Facebook, which focuses on personal social networking, the main purpose of LinkedIn is for people to make professional contacts with others who are in a similar field of employment. LinkedIn gives users the ability to make a status update, which can be a short message or announcement, that all of the user's contacts can view.
Log in to your LinkedIn account.
Enter the text of your announcement into the blank field labeled "Share an Update." You will see your profile picture with a talk bubble located directly to the left of the blank field. The announcement is limited to 140 characters. You can paste a link in the status update that takes the reader to more details about your announcement. Unlike Facebook or Twitter, you cannot "tag" other users in a LinkedIn status update.
Click "Share" to post your announcement to LinkedIn, where all your contacts can view the announcement.
