I was going through Dropbox forums, apparently they plan to drop the public folder methods for the new users but the old users are safe for now. I have 9 GB of files on there and I don't want all my links to become invalid for no good reason. So, I have started using other services. Currently I am using 4Sync and Google Drive. There is a service called SugarSync that I am willing to give a shot as well.

Yes, I know Google monitors your data but if it's for the CDN then it's NOT a big deal, plus Google Drive is cheaper than Dropbox. I am not planning to leave Dropbox but it's best to keep an eye on future.
I am also clearing my Firefox tabs, so expected some unfinished threads.
