Yes, I changed the blog layout (and will rework the header sometime).
The old layout had a heavy, amateurish look (my own work and now lost). It reminded me of layouts I did in the 1990's, and that's certainly no good sign.
It was impossible to update because blogger disabled most options; I wasn't able to add a background tile either through the blogger interface or even in the source code (or what posed as such). It was frozen beyond repair.
I hope the new layout will be more relaxing to the reader's eye. The texts are meant to be demanding, not the layout!
