I did last year but just couldn't be bothered this year.
I started keeping a list a couple of years ago, using an MSN Spaces blog. My reading has actually changed because of this. The first year I ended up reading a book title for each letter of the alphabet, the second year I alternated fiction and non-fiction with a month of each. No theme this year, I'm just reading subjects which interest me.
I think what you did is so creative and interesting
I also think a book list of any kind kept anywhere is a another gift we give ourselves from reading
