In part 1 I looked at some of the ways you can improve your use of LinkedIn updates, particularly feeding in updates from Twitter. You can also post updates directly in LinkedIn, using the "Share an update" dialogue at the top of the screen.
This useful dialogue allows you to attach a link to an external article, such as a blog post, either by clicking on "Attach a link" and pasting the link into the box which appears, or directly - paste the link into the share dialogue, and watch everything update. You can also provide additional text in the share dialogue.
If you are feeding updates from Twitter into LinkedIn, there is a pitfall to avoid however, which is posting the same update twice, once via Twitter and then separately via the direct LinkedIn update. Your connections on LinkedIn will see two updates, identical, often next to each other, like this (admittedly rather contrived) example:
This can becoming annoying very quickly, and could lead to your updates being hidden by others, something which you obviously want to avoid.
