We're happy to announce the relaunch of the SlideShare app on Facebook. We have completely rebuilt it, integrated the latest Facebook changes and made it more useful. You can create an account on the SlideShare Facebook app and link it to your regular SlideShare.net account. How does that help? Well, once you do that, any presentations (or documents) you upload on SlideShare will instantly be available on Facebook or if you upload them on Facebook, they'll be available on SlideShare. It doesn't end there, of course. If you've added the SlideShare app for LinkedIn and linked it your SlideShare account there, your presentations will automatically be visible on LinkedIn too! In fact we strongly recommend you link both your LinkedIn & Facebook accounts to your SlideShare.net account. Once this happens, you have a HOLY TRIAD in place. Upload to any one- SlideShare, Facebook or LinkedIn and it will shows up instantly on all three. Isn't that really cool? More details on the blog :
