I certainly wouldn’t be surprised if this is a service that LinkedIn itself begins providing in the near future. JobChangeNotifier.com does exactly what its name suggests: it lets you know when any person who is part of your professional network has got a new job. This information is delivered in the shape of a timely email, letting you know exactly where and when the person has been hired.
This is a useful service bar none. It simplifies knowing when people who could help you in your professional career have been promoted, and (consequently) are in a position where they will be able to pull some rank and aid you in your search for a better job. It can also let those who are keen on working at any specific company but who refrain from sending their resumes in for consideration because an antagonist works there. Well, a service like JobChangeNotifier is going to let you know that the time to approach that company has come.
And JobChangeNotifier.com lets you do all that for free. As long as you have a LinkedIn profile (and some contacts to go with it, of course) you will be able to use it as intended.
