Don't Wanna Memorize Numbers? Call Someone's Twitter Handle InsteadSam Biddle3/04/11 9:40pm22EditPromoteGo to permalinkI have no idea what my mom's cell phone number is. I don't think I've ever known the phone number of a girlfriend. Why would I? You probably don't either! Contact lists killed them. But web service Go800 wants to skip the whole number thing entirely, letting you hit people via their Twitter handle to connect a call.
