The problem with retweets: How do you correct an error that goes viral?

From Mat Honan at Wired.com: 

Here’s the problem with the way the current system works. Let’s say you tweet something that turns out to be incorrect to your 100 followers. Let’s say 5 of those retweet it to their 100 followers. At this point, some 595 potential people have seen it. (Or at least spambots, but bear with me.) You realize your error, and issue a correction on your Twitter feed. Your 100 original followers may see the update, but it leaves 495 who do not unless those same five people again retweet you. 

In short, while the automatic retweet button on Twitter lets people spread information far and wide beyond your followers, there’s no way to makes sure those same people see your attempts to correct it.
