Eye-Fi already makes it simple to wirelessly upload photos to your favorite sharing sites, even on the go, but now it alerts your friends as well. As of today, users can integrate their Eye-Fi card with Twitter so that your followers will instantly know you’ve uploaded photos, and will receive a link to the new pics. You can even customize the message that your friends will see. The company also now allows users to publish RSS feeds of photos to Google Reader, My Yahoo!, bloglines, newsgator, Pageflakes, netvibes, and others. Now, just make sure you’re happy with all your photos before you add your Twitter account to the mix. The last thing you need is to accidentally broadcast those debaucharous photos you took last weekend by simply turning on the camera in the vicinity of your router.
