I will someday (meaning, if you poke me a few times I'll get around to it) do the spreadsheet for my booklog. I have a preliminary one, but I'd like to put together a more elegant one tracking books I read, authors I read, gender, genre, YA or not, and such. By month and cumulatively, with all the pie charts in the world. All of them. I might need cake charts.

It wouldn't actually be hard to set up, but the data entry could be a pain.
