There's some hilarious irony in these placeholders recommending limiting to 50 characters and wrapping to 72, then blasting past those limits.
Rather than suggesting those in the text (while we think they're good ideas, and enforce them for our stuff, not everyone does), let's just show by example what good lengths are.

I think the placeholder for new items should go at the end of the list. This is where new items show up, so it's like you're "filling in" the dashed box with the thing you're uploading.
