A friend of mine, older, but also online like me, sorted her online friends into at least two groups: a) people I’ve met offline, b) people I haven’t met offline.
Another friend of mine, same age, recently did a website project and hired a programmer from Bangladesh. Obviously, the two have never met offline, yet they are working closely together. Online. Like the most of us.
Which begs the questions: how important is it to meet offline? Does it change anything? Would you continue working with your online contacts if you were to meet them offline?
And: how productive is online work with regard to the Wikipedia and other social tools — compared to the offline output of a project?
