As some readers may have noticed earlier, the underlying software of the ETH blogging service was upgraded today. It seems to have worked fine (if any problem arises, please indicate them in comments), the only problem being that the upgraded theme I use has switched its rendering of the <em> tag from italic to bold. And as you can see, the default WordPress editor automatically transforms italic tags into emphatic ones. Unfortunately, I still do minor changes of most posts on this editor, so it will probably require some thought how to correct this (hopefully the support people will accept to change the CSS code of the theme)…
At worse, I can switch to another theme, since not all seem to have this problem.
(Note that if you read the posts through Google Reader or something similar, the problem will not appear).
