I picked the nice twenty eleven theme by wordpress, tweaked the background a bit… and will tweak a couple of other points (like slightly bigger menu buttons, test also other type of commenting, highlight comments, change sidebar font… small things like that).
And most importantly: this works great on mobile devices. Earlier my site was bad to read on mobile.
If you happen to notice something strange somewhere (you know, like errors)… feel free to mention. Any comments are also most appreciated.
