Thanks for the article! I didn't hear about ownCloud (or similar projects) before, I'm already reading manual (http://doc.owncloud.org/server/5.0/admin_manual/) and will be installing ownCloud on my VPS today. I had doubts about giving Google (or any other company) so much of my data (not only emails, but schedule, contacts etc.) - now I found a great solution. I love HN.
