Why I changed my twitter picture

In this blog I will explain why I changed my twitter picture.

After a presentation I gave at the University of Utrecht someone in the audience came up to me and asked the following question: "Can I follow you on twitter?"

This flattering request made one thing clear. My twitter pictures has no relation with me. How could anybody know my account from the following picture?

In order to be more accessible, I changed my picture. For now I have changed it to the picture I use for my blog. Maybe in the future I will pick a fancier picture.
