I am Matthias Melcher. Born 1953; studied maths in Heidelberg and Glasgow; from 1981 to 2016 in the Computer Center of the University. Initially in network infrastructure. Since the early gopher days, I have drifted more and more towards content.
My blog name “x28” means nothing, it
is was just my userid since nearly 30 years. See also my German blog on eLearning, Social / Collaboration Software, and Knowledge Management.
