twitter is a tiny tiny tiny "potential audience" and is predominantly a very small "niche" audience of American's that the Gates charity is likely loathed by and thus twitter as a tiny app / website offers little to no value to an organisation like the Gates Foundation who can get million fold more value from normal media comms / marcoms and better bang for their buck than the loathing hater filled tiny little dying twitter app / website.. twitter is all but dead anyway..
