Not many people on Twitter know that their tweets actually have expiration dates. Sure, they will always appear in your twitter stream, but after a matter of days, they are already unsearchable. Twitter needed to do this because of the website’s popularity and huge number of users. However, this is not good news for users interested in data-mining, because twits will not be able to be found through Twitter’s search engine just days after they are tweeted.
Thankfully, there are plugins, applications and various other methods that you can use in order to back up not only your tweets, but the tweets of other people that you might want to archive. Here are three different methods to backup your tweets and save them either as PDFs, or Microsoft Excel and Outlook formats.
