All I was going to add is, if possible, attach a piece of white cardboard (or similar) to the "topside" of you flash when using bounce.
You'll get not only the soft light of the bounce, but also a more "direct" fill light on your subjects.
Makes for a good effect IMHO.
That's a good tip. A better bounce card is also a very inexpensive way to go.

However, a static card is not always so useful when you start angling the flash head to the left or right. Flip it around the other way and a taped card will act as a gobo and block light from going forward.
I use a Demb Big Flip-it for just this reason (didn't use it in these examples). It straps to the flash head with velcro and has a hinge so you can easily flip it up when you need it or flip it out of the way.
