Why do you have to post a title when you make an announcement on the main page?  Doesn't make much sense.
Do they both show?

I think so you can keep track of them in the "My shouts" section, in "Your Stuff". Some people make so many, they might have to go back and edit, etc. Don't think it's a inconvenience anyway - do you?

I'm not sure.  I didn't understand why it needed a title, and if it showed in the announcement.

Yes, it really doesn't make sense.... it doesn't show, except to you, in your list of shouts.
