Fine Cooking also recently did an article on cheesecake, and their advice is to add the eggs last and one at a time, just until blended. The reason is because over-mixing will incorporate too much air into the cheesecake and make it puff like a soufflé in the oven. When it cools, the cake will collapse and the top will crack.
We also think it's a good idea to gently beat each egg before adding it to the cheesecake batter just to loosen the yolk. This will help it incorporate more easily and quickly.
