A couple of the more interesting ones:
Chirpscreen is a fun little app that shows you what your friends are up to on Twitter, Facebook, and Flickr. It also tracks eBay keywords for you. You can get your updates in a desktop window or on your screensaver. It’s like a more graphical version of Friendfeed, and like Friendfeed (and other Twitter clients), you can also reply back to posts you see in the tool. It feels like a shallow app, but that’s just because it’s pretty. News today: Mac version now available.
JobScore. This is a clever recruiting service. Not only can you outsource your company’s jobs page to this company, but it will track applications to your jobs. And in a neat twist, it lets you make money from the applicants you don’t hire. See previous coverage: Jobscore pays you for recruiting rejects. Update: launching some of the features now, as well as free credits now if you sign up.
