"When you tweet something, that tweet lasts forever (persistence); it can be easily retweeted, tweaked and retweeted, or slapped on a t-shirt (replicability); it can be found with some speedy Googling, and if deleted, scooped up from the darkweb (searchability); and no matter who you think your followers are, that tweet may eventually end up on the interface of an employer, creepy dude, or your born/unborn children (invisible audiences)."
