Bow to the all-mighty strikethrough text. If someone calls you out on an error, fix it and fix it fast, but keep the mistake in with the cross out, so you don’t hide the mistake.
This shows transparency, a story’s growth and, really, keeps you, the reporter, more motivated to get it right the first time.
Print journalists take seriously the notion that what goes on the page stays on the page, but often hid behind a correction running later, smaller and being ignored. The Web combines the best — we stand by what we publish because we won’t erase a mistake.
I love the use of letting your readers kno when a story is ‘Updated’ and listing those changes at top or the bottom of the story for all your readers to see.
Transparency cannot be lost, and, like attribution, it doesn’t have to be.
