If you use both LinkedIn and Twitter, you can easily create a list on Twitter of people you are connected with on LinkedIn.
How to do that?
1) Add the Tweets Application to your LinkedIn Profile (via More/Application Directory).
2) The Tweets Application now also appears under “More”. Click on it.
3) Click on “Connections” (second tab on top of this new page).
4) Choose “Save as Twitter List”.
In my opinion it makes more sense to create your own lists on Twitter depending on your relationship with each Twitter user you are following or depending on the topic, but this is another way LinkedIn helps with a free tool to keep up to date with your network.
To your success !
