Yes, cloud services like Dropbox make it easy to share folders through public directories and links, but you still have to put those folders in the cloud in the first place. Wouldn't you rather share them straight from your PC? BitTorrent hopes to make things that direct with its big Sync 1.4 update. Now, you can share folders with others just by giving them web links; you don't have to wait for the files to reach a remote server, or rely on Sync's slightly more obtuse Key system. You don't have to sign up for an account, either, and you can still limit access to prevent others from messing with precious documents. About the only headache is that your recipient needs Sync, although BitTorrent promises that it will walk first-timers through the process.
