Sure, there's a lot of rubbish still being written in the name of customer and employee communication, and no-one would expect the PEC to put everything right even in 30 years. It's the target, the aspiration that is troubling: plain english.
While the good fight is being fought against over-complication and obscure vocabulary there's a greater good we can all aim for. Why shouldn't the language of business be rich, entertaining and memorable? Clear is good; dull is not.
So, no apologies from me for coming back to a theme I've covered before. While some can only hope to be plain, do what you can to stick out from the crowd - use language that's alive.
