A somewhat simple interpretation. It is pervasive because it's common in corporate circles, more so when they are US institutions. Its use for effect may be a few people I don't disagree, but don't assume it's people simply trying to climb the ladder or be seen as a guru because it isn't, it's just an example of changing times and language.
I suggest you are less prone to recognising it because it's more pervasive than you think, Americanisms etc are changing our language, you tend to notice things more when they are not in your normal way of life, that was my point. I hear internet and geek speak (for want of a better word) all the time, not least from technical teams.
You also show my point as you seem think people use the language simply because they want to be seen as something they are not, which I don't agree with. A modern vocabulary is not something that climbs you up the corporate ladder or makes you a guru, you need to be good and those who don't seek the climb often find it easier to criticise and sneer, which was also my point. I say again, I hate the use of buzzwords, I appreciate and aspire to eloquence but I like words, nice English old fashioned words used appropriately.
