Jack Vinson writes about blogs again and shares a quote from Martin Roell in his blogpost : "Blogs are like emails to someone you don't know yet". This reminds me of two quotes that have stayed with me lately:
One via my colleague who overheard two small boys in Burkina Faso. The first boy asked the second boy what a computer was ('qu'est-ce que c'est un ordinateur?'). The answer was: 'C'est une machine pour parler aux blancs.' (it's a machine to talk to the white people).
Angelica Senders from ICCO shared the other quote (don't know where she got it): "if you don't know how to cycle, walking is always faster": in the context of using new technologies or new tools to communicate. This ressembles the quote about talking about tagging to people who have never tagged like 'talking about sex to virgins'. (read this in a blog somewhere too).
Though I'm not such slogan person, a good one liner or slogan which captures an important notion can have its value, because it really sticks in your head. I think it sticks because you recognise it's a good compressed representation of reality.
