The big thing right now seems to be weighing ingredients. Cooking Light has switched to weights for their baking recipes, and I've seen a few other bloggers rhapsodizing about the importance of weighing your ingredients.
I would certainly never tell anyone not to weigh. Kitchen scales can be fun, and I'm sure the accuracy is good to have. But I've never, ever, had a recipe not turn out because of, well, because of anything other than "I entirely forgot to add something," so I don't understand all the excitement.
