Ever wanted to make your Twitter followers believe you're in one place when you're really somewhere else? Please Don't Stalk Me is a web app that allows you to attach any location you want to a tweet.
Why you would want to fake your location data is not our concern, but we could see it being handy for cases when you're supposed to be home sick rather than out partying. You could also use it to make it look like you're at home when you're off on holidays, although it's probably easiest to just turn off location information altogether. Please Don't Stalk Me only works when you have tweet location turned on through Twitter itself.
