I recently had to share some documents with friends. The problem was that the online sharing websites had little to offer with what we had to do and that was sharing/blogging/editing/versioning at the same time.  And then I found zajet.com, which made the whole thing simple and fun.

This website allows you to share almost anything you want (the file size is limited though, only 2 MB per file which is really a shame; make it at least 5 guys!). You are given your own page when you sign up and then in that page you can blog/post articles/share files etc. A nifty little feature is that your own widgets can be added to your page.
