When people speak in shortened English, and use obscure abbreviations (like “ADV”), I get extremely annoyed. When/if you want to communicate properly, you should never be using references without at least explaining what they mean, or are referring to. It is inconsiderate and rude. I see it happen all the time in forums. I am getting too old, and curmudgeonly to tolerate “insider” talk. The OTL magazine also has baffling writers, who often have referenced subjects/people/ideas that do not compute.
