If you’re a regular Twitter user you may have noticed that via the Twitter web site you can’t access all of your old tweets. Additionally, what would happen if Twitter suddenly lost all of your tweets tomorrow? So, how about backing up your tweets? There are several online services for doing just that but the one I use is BackupMyTweets (a section of the larger BackupMy.Net service.) Just sign up, connect to your Twitter account and the service does the rest. Once backed up, you can download your Tweets in HTML, JSON, and XML formats.
