Many of you are by now sick of me banging on about free software, and why open formats are so important. Many of you also probably still don't understand why this is so important to me, or why I insist on making such a big deal out of what is, when all's said and done, a pretty esoteric concept.
Maybe this video will manage to express what I've failed to get across. This is why openness is important. This is why it worries me so much that my local council stores information about me (and information which is important to me) in the proprietary .doc format. This is why I'm glad my phone runs Android, an operating system with an open source code. This is why I replaced the router that my ISP sent me with one I built myself, and this is why I will never, ever use Internet Explorer.
Seriously. I know I get on my smug soapbox so often it has its own postal district, but just take 15 minutes out of your day to watch this video - and if, at the end of it, you want to know how to make your tech life more open, give me a shout.
