It's common for one person to have multiple feeds/identities, so this is less of a problem than you might expect. There's no structured way to indicate that 2 feeds are the same person (aka #sameAs), but you can easily link to the other feed and just say “this is also me” (because your audience is a bunch of humans that mostly pass the Turing test). Because of this, we get the bonus feature that you can easily follow a different set of feeds on different devices — e.g. perhaps on your phone you want feeds you're less likely to reply to, because you prefer typing on a physical keyboard.
