I don't mind; I wish people would tell me my changelogs suck before they
get committed though; I can still fix them at that point.

It not only helps others, but also myself. I've on many occasion kicked
myself for not writing clearer changelogs when investigating something
months (or years) after I wrote the initial code.

The problem is that I mostly know what I mean when I write it and I'm
not very good at writing in the first place -- real changelogs often
take longer to write than the actual code. But I guess that's true for
many people.

Anyway.. I'm ever trying to write better changelogs, but alas there's
also always far more room for improvement :-)
