Why was the Library of Congress archiving all tweets?

Since 2010, Library of Congress has been archiving every single public tweet: Yours, ours, the president's.
But today, the institution announced it will no longer archive every one of our status updates, opinion threads, and "big if true"s. As of Jan. 1, the library will only acquire tweets "on a very selective basis."
The library says it began archiving tweets "for the same reason it collects other materials — to acquire and preserve a record of knowledge and creativity for Congress and the American people." The archive stretches back to Twitter's beginning, in 2006.
But as anyone who's been following along can attest, Twitter and the way it's used has changed since then. First and foremost from a collection perspective: the sheer number of tweets.
"The volume of tweets and related transactions has evolved and increased dramatically since the initial agreement was signed," the library explains in a white paper accompanying the announcement.
The library doesn't say how many tweets it has in its collection now, but in 2013, it said it had already amassed 170 billion tweets, at a rate of half a billion tweets a day.
