Spayed Edges: Love them or Leave them?

I got myself a new bookshelf last week as I was seriously running out of storage space. When I was liberating some of my books from the double rows I had them stacked in I noticed that there were a fair few with sprayed edges. They look so bright and cheerful on a shelf I think this is one of my favourite additions to books over the last few years (although I would like to see little pictures at the start of chapters make a come back too!)

What do you think? Are you a fan of sprayed edges too?
