Headline feed not updating
Once you start typing in an update box, a drop-down menu next to "Post Settings" will appear at the bottom of the box.
Options include "Public," "Public Twitter," and "Connections." Selecting "Public" gives your update the most exposure because, as Linked In Help says, your post may appear on: In most cases, the Public option is the best choice.
If you click on the "Write an article on Linked In" link, a Linked In blog form page will open, allowing you to add an article to your Profile.
[Please note that Linked In continuously changes and rearranges functionality and features to improve the user experience, and they don't roll out those changes to everyone at once.
The benefit here is that these people will be notified that you’ve mentioned them.
Linked In also offers you the ability to share a photo (or other image), share a video, or upload a document to Linked In, depending on which of the left 3 icons in the image above.
Additionally, you’ll be building brand evangelism for them. People search Linked In using relevant keywords and phrases to find people like you.
When these hashtags appear in your updates feed, people who can help you with your career goals are more likely to find those updates and take a look at your Linked In Profile.
If you’re in a "stealth job search," the last thing you want to do is alert your current employer to the fact that you’re looking.
So, take precautions to keep people from noticing that you’re working on your Profile content, a telltale sign that you may be looking for a new job.
