Hello Dolly is the hill I am willing to die on. :)

Seriously, I like that we include a simple plugin like that that can also be a little fun. I wouldn't mind getting rid of it, but I'd want to replace it with something else.

For example, I think a cool default plugin would be a randomized translation of "Howdy, Justin Tadlock" in the toolbar. That way, everyone can share in all the languages WordPress is available in.
