My biggest bug-bears is the use of the words paradigm, synergy and holistic.
I agree especially with paradigm, which is why I used it somewhere above. Its falling out of favour again now so I guess the drivel-creators are trying to find something new. What really annoys me is that paradigm was/is only used in the context of change (new paradigm, paradigm shift etc). This meant that they can never express what the current "paradigm" is which suited them because lets face it these types don't have a clue whats going on anyway
Synergy and holistic whilst over-complicating nice simple English at least had some meaning...well occasionally...well I think I remember them being used correctly once
