I don't see dilution of the definition as a problem. Video games used to be geeky. Now everyone plays video games. Everyone is geeky. To paraphrase Gordon Gekko, 'Geeky is Good.' And for the record, many of them consider themselves geeks for legitimately geeky things, not 'playing angry birds on their phone' as you so derisively mention.
