This App Shows What You Were Tweeting Up to 9 Years Ago. I suppose that there are people who regret things they said 9 years ago. Haven't we all? But, in the Internet Age, we are creating a record of our stupidity or crassness or whatever that will last long after we are gone. For lawyers, this Internet history is a rich motherlode of information that can be mined for relevant data in litigation. For prospective employers, it can be a window into the true nature of the prospective employee. For parents and stalkers, it can be a way to follow the objects of their affection. Yes, it can be a tool to reach an audience; as many entertainers and politicians have shown. But, what if someone could follow your tweets from long ago? Now, you can, and there are apps out there to help you. In the case of iOS, the new Tweetstory app makes it easy. So, be careful what you tweet. Someone will be watching, and they have a long memory.
