Want to start an argument with a new acquaintance? Talk about politics. Want to run off a potential customer you’ve never met? Post to social media about politics. Inman News contributor Jimmy Burgess has a whole list of topics to avoid online for the good of your business, and politics floats to the top as the presidential race gathers momentum. Jimmy’s other no-no’s include angry or denigrating posts about any person or business — the negativity rebounds onto the writer — and “party posts” that show too much fun.
