Absolutely! Although practically every time I rec something, I think - well, that could have gone into X category as well, and when I see other people's recs, I find myself thinking, I hope you've got something for X category because this one would have fitted it really well...

There was a WTF challenge several years ago, which I started to participate in but never finished all the categories. I bet we could have had a February WTF asking for stories in all kinds of bizarre categories. One day definitely isn't enough!
