The idea is to follow the updates of an entity, where Google I/O is going to be run by more than one person, all of which could and should provide updates for the single entity. Would you rather follow the updates of otherwise disconnected employees of Google who happen to have updates for Google I/O? Who's to say the updates are even from Google employees and not out-sourced organizer? Should we really request the organizers to use their personal accounts to give updates for the event, while disinterested followers -- friends, family, or otherwise -- are inundated with Google I/O updates?

You can grind your Facebook axe elsewhere, but unless you have a useful solution to add to your problem, can you grind your unrelated axe elsewhere?
