I think footnotes are a strange literary phenomenon. They are an
interjection that is allowed to have its own lexical formating, That in no way interrupts the tempo, rhyming scheme, or other literary devices of the sentence that contains it. On top of that, by nature of its identity, is known to not have a continuous contextual flow with the rest of the content. Really a wonderful way to represent the way that words will trigger associations with other thoughts.
Their other use, is somewhat less interesting, to cite a source of information.
I bring all this up because it seems that though if thought about, it is already known, It is not being focused on. are there other reasonable formating methods that can do both these things with similar grace, or is it in fact a need that .epubs next incarnation needs to address?

I have always felt that english needed a sarcasm mark... That would help prevent a
sarchasm while reading, or messaging online.
