I like some of the new file share features that are now available since the upgrade to SkyDrive. The key is that you can generate a share down to the level of the individual file and can even lock it down to viewing, view + edit and sharing with the general public. They have also made it easier to share to your social networks as well by including that capability as an option. Take a look at this video to see this in action.
