Jobster are doing great work in the corporate space, where they have around 400 customers paying thousands of dollars per month - 15 percent of Fortune 100 employers use their services. But turning Recruiting.com into the clichéd "Digg for Recruiting" seems like a wholly uninspired move - there hasn't even been an attempt to create a more innovative interface. Coming so soon after the relaunch of Jobster.com as "MySpace for Jobs", it seems that they're just cloning established sites and adding a job-related spin. These consumer-facing apps certainly help to generate some buzz around the company, but they're unlikely to take off - the corporate side is where Jobster will continue to prosper.
In fact, Jobster joins a host of services trying to create Digg clones in their various niches - there's already more than one Digg for video, a Digg for podcasts, a Digg for cars and Nooz's attempt to build a version for MySpace users. There's also Netscape's unabashed Digg clone and thousands of sites built on the open-source Pligg software. It's too early to tell whether any of these sites will take off, but it's probably safe to say that most won't be around in a year's time.
