Paradoxically my registration to social networks have been motivated by my professional life. I registered in Facebook because I was organizing a public talk. A recent grant application form asks about a website. I decided to buy the domain name www.astrowing.eu. I was first surprised that the domain has not been used before. Also I am glad I can use the eu instead of a country since I do feel I live in Europe. I will keep this blog site alive since it has hosted my first blogs for free.
