What's the hole in the middle mean?

If there's a hole, doesn't that just mean less donut to eat? 

Anyways, I love doughnuts!  Who doesn't?  Fried dough with frosting?  Happy little sprinkles Bob Ross would've been proud of? What could possibly be wrong with that?

I made a few today.  I'm still perfecting the technique, but I really like the chocolate ones with sprinkles.
