One of the fun things (for me) about e-publishing involves font selection.
Yes, you read that right: font selection. Crown me king of the geeks.
But think about it. Book covers are different in the digital era. They are an electronic "button" with which a reader might investigate or purchase your book. Fonts must be readable on small icons and draw in a reader's attention. They should convey a message about the book, too.
I could spend hours looking at fonts...
Unfortunately not much else would get done.

Don't blame me if you accomplish nothing today.
