LinkedIn is now the second-largest social network in the United States, finally surpassing Myspace with nearly 34 million unique visitors. Alongside this success, Roger Lee has created an unofficial addition to LinkedIn called Job Change Notifier. According to TechCrunch, the service uses LinkedIn’s API to let you know when any of your LinkedIn contacts update their jobs on the site.
Lee works for PaperG, a company dedicated to local online advertising services. He says that Job Change Notifier already tracks more than 300,000 LinkedIn profiles, and that LinkedIn employees are interested in his site.
