When I started in SEO business almost have a year ago, I have been shunt into Matt Cutts, head of Google's webspam team. Reading his blog articles, i did not only get insights into Google, but also in his person. I got to know, that he starts challenges which would endure 30 days, usually. For one of those, he decided to switch from Windows to Ubuntu, and he eventually he kept using it. The latest challenge was to replace his iPhone with Android based Nexus One, and he does not seem to roll back, too.
In our time, when everything is, goes and is going to be more and more web based, my impression is that many users do not think about where they put their data, how secure the provider is and which control they have. Especially with the rise of software-as-a-service models you need to be sure to know what happens with your data, somewhere in the cloudy somewhat. Who is you email provider and who can read your mails? Are there Backdoors? Should i upload my pictures to flickr? Where can i safely send private and possibly sensitive messages?
