Everyone loves Tweetdeck, but when I changed Twitter accounts, I wanted a way to backup my Groups. Thus RogerThat was born.
This website allows you to quickly back up Tweetdeck Groups in text format - and also follow/unfollow people on mass.
This is useful if you have a TD Group you'd like to mass-unfollow, or if you find a list of Twitter users you'd like to mass-follow.
