HN's software should probably replace non-trailing exclamation points with something rather than nothing.

I took the Extra bit out of the title for now, since it isn't needed and I suppose might confuse younger readers.

What does this "Extra!" bit mean?

When breaking news came out a newspaper would sometimes publish an extra edition to go out in the afternoon. The paperboys would stereotypically say, “Extra! Extra! Read all about it!”

The Wikipedia article [1] is to the point here, and even explains why they went away: the introduction of radio meant that a one-off printing for news didn’t make sense as everyone heard it on the radio.

At some point paperboys will need to be explained also, and some time after that, newspapers.

You see, we had things called computers, which were like an interface between you and the network...
