I should edit that to say that it keeps all the deleted tweets that it pulls in while running. If I'm not running tweetdeck on my phone and he posts and erases stuff before I fire it up it never pulls them in. It's not a time machine. But, it's kind of motivaiton for me to always have tweetdeck running and pushing updates throughout the day (subsequently draining my battery). For example, i never saw the original got a job for $50k with the rockies tweets. those I only got from Nick Wright re-tweeting them and he erased them before I got on. But, I have all the deleted PS3 tweets and his deleted stuff arguing back and forth with nick wright.
