Just a bit of web-tech administrivia for those of you interested in such things. Having always displayed a “Valid XHTML” button discretely on this site, I’ve just discovered that YouTube has been making a liar out of me ever since I started embedding their videos.
I’m sure there must be a way of sorting it out, but I really can’t be arsed right now. Until I look into it though, I’ve removed the “Valid XHTML” tag.
Other YouTube embedders beware!
