During the last years, I refused to join to Facebook, Instagram or Twitter. I entered Flickr ten years ago, and my webpage has been working for twelve years. Recently, my webpage, designed by Massimo Vignelli, has been transformed into a responsive web by Alejandro Sevilla. And now, I am in Twitter.
I hope this is a positive step, in a world riding on-line more and more at vertiginous speed. At last, in a sunny day at the beginnings of March 2017, we are in Twitter.
