The title confused me for a second because there’s no indication this is /r/PuertoRuco. I initially read the title as someone going back into public relations.
This is why abbreviations should be avoided as much as possible, unless the writer can be almost certain that every reader will know the abbreviation.
Well, it was posted to /r/PuertoRico, so the abbreviation is pretty unambiguous within that context. It should have been expanded when posting this to HN, though.
