File this under frightening/awesome: “Every public tweet, ever, since Twitter’s inception in March 2006, will be archived digitally at the Library of Congress.” The only posts on my Twitter are the automatic reprints from Tumblr when I update this blog, so now the Library of Congress will archive the automatic update on Twitter that Tumblr makes when I publish this post, which is a link to their blog post (which they also posted on their Twitter, and then archived digitally).
