Zeldman:
Kids today are more likely to respond to a blog post on Twitter than in the article’s comments section; so we’ve collocated our comments on Twitter. Share a tweet-length response here, and, with your permission, it will go there. If you are moved to respond with more than 140 characters, post the response on your website, and it will show up here. Clever, these Americans.
A pretty neat idea, it will be interesting to see how this plays out long term.
