What do you think about forcing punters to kick to returners - rather than just kicking it out of bounds?
One side of the debate loves the chess match that you get from it (in terms of field position). It also demonstrates the punter's skill. I think it's neat seeing a punt go out of bounds inside the 5 - that is skill!
The other side loves the excitement of a return. A return for a touchdown is usually the biggest play of a game, and it's always fun (or scary!) when a returner gets his hands on the ball. Watching a returner beating even 2 or 3 guys is great, let alone when he takes it all the way!
Personally, I think that punts and singles should be treated similarly - as follows: If the punt/missed FG bounces in the field of play at least once, and then goes out, then it's legal/a single is awarded. If the kick goes straight out of bounds, without ever touching the field, then it's illegal/no single.
I think a good penalty for punting it out of bounds would be L10, repeat down ...
