This will no doubt be useful for LinkedIn members who are looking at their careers and earnings potential over the years ahead.  It also helps to keep us thinking that LinkedIn is still really a fancy Jobs site, yet it is so much more than that.

At the end of the day, LinkedIn is a piece of software, and like any other software asset that you use in your business, it's vital that you know how to use it properly or it will be unlikely that you'll realise its full potential.

I always ask audiences at conferences for a show of hands for who is on LinkedIn and almost everyone raises their hand. But when I then ask who knows why they are on the site, hardly any hands go up.

LinkedIn is a powerful real-time networking platform, PR tool, thought-leadership community, sales lead machine and so much more.

It's great that you can now check out how your salary compares with others, but invest time in learning how to really use LinkedIn and you instantly position yourself better to increase your earnings.
