The title that is much longer than is seemly for the width of the sidebar archives list

I used to have a rule about the length of blog post titles: they had to be short enough to fit into just one line of the sidebar. I don't know how or why I developed this rule, and it took me more than a year to realise the thing was there, despite the fact that obeying it - trying to make titles short - got me tangled up in knots.

Stupid behaviour due to a stupid rule, or a stupid rule due to stupid behaviour? Which comes first, the idiot or the idiocy?

I don't know, strangely enough.
