Prune Your Fruit Trees Now or Wait for First Bloom?

I saw a post recently on Tri-City Gardeners where a woman was asking if she should prune now or wait. She said she was getting mixed messages from her gardening books and the information she's found on the web.

She has a nectarine and a plum tree. Both are too tall and scraggly and need to be pruned. So should she wait until they bloom or go for it?

Comments on group pages like this are always extremely helpful. It looks like the answer is prune now!

Nearly all the answers suggested that pruning in February is the best idea. Granted, there are others that say that you won't get fruit if you prune when the tree is dormant. But most of the comments seem to believe that pruning while the tree is dormant will cause the least amount of stress on the tree and produce ample fruit.
