Was having a conversation with a mate t'other weekend - I was telling him how my new obsessive compulsion is to shift the baseline of all @ symbols down a tad. They always seem to sit too high.
He asked whether that sort of thing really stands out, and if it's worth taking the time to do so... Made me think. No one is really going to notice that all the a glyphs in the @ symbols are sitting more in suit with the other letterforms... But that's the point. You don't want people to notice.
Just saw this on a few different blogs... Think it sums it all up pretty well.
