Sharing is Caring, privacy, content filtering, and applications.

Welcome to the information age, where the governing principles of the world are undefined and misguided. Them being misguided without being defined is rather odd without thinking about the underlying factors. Big business has played a large part int his as well as storage capacities being incredibly cheap. The internet is a wonderful and dangerous place. Anytime you send/share information with another user, that information has the possibility of being read, tracked, traced, copied, and modified. This is a much larger threat then before. The primary reason being that storage space is incredibly cheap and getting cheaper, and that documents are generally rather small.

With everything said, there are times when you want to share. There are plenty of useful tools for this, but remember that when you use a tool that you do not own, you are at the full discretion of the provider. A few lovely tools are: Dropbox, Google drive, Idrive, and Skydrive.

Out of all of these. My favorites are Google drive and Dropbox. Dropbox is rather nice because it cloud storage is the only thing that they do. Additionally, it is very easy and is not email specific. Additionally they have a cool feature that provides you with additional space based on the number of people you invite, to a maximum I believe of 15GB's. Google drive is also pretty neat.  It has a lot of nice sync features, additionally it has a very nice sharing features making it easy to share with who you want. 

However, it is a bit of a pain to setup on GNU/Linux and doesn't work all that well even after you setup. Sharing is both a gift and a curse. It is easy to share, and because it is easy to share things that you didn't want shared can easily find themselves on the web. After something has been on the web and has been viewed by many different people it is almost impossibly to stop people from sharing the information.
