a or the most fictional renowned expert? or just "world renowned expert" on some sun sucking stuff that does jazzy stuff with elecrtro magnetic particles known as photons? It's probably Matt Cutts fault he has flaws to you know!
As an expert I think the first thing to do is accept that not everyone else is otherwise they wouldn't be searching for information. Alienating your audience by refusing to use colloquial terms is just setting an aloof standard. I do see your point though.
Google finds out users search intent, semantic search relationships before giving the best possible relevant results to the users. So a relevant keyword or even the nearest matched synonym might provide a different result at times.
