I do not see the point of archiving the billions of tweets on twitter in the library of congress. If the intention is for historical purposes I would contend that billions of tweets are too much to sift through to be historically relevant. Historians already have enough trouble sifting through the surplus of information out there. It would be much more productive not logging the tweets themselves but rather the trending topics. With the trending topics you can keep track of what the hot button issues of the times are. Seeing what the most searched topics are on search engines would also be a suitable tool for historians. Blog posts and things of that nature are much more formidable tools for historians and are all meant to be publicized.
My biggest problem with this though is the privacy issue. Not so much so about the tweets but about where it made lead. This could be the start of a troubling trend. It seems like the government time and time again moves the line governing privacy closer and closer into our personal space. This is the first step in a process that’s sure to get worse. We should learn from the Allie’s mistake in world war 2 and stop Hitler at Munich. We need to draw a line.
