Tripps, your use of `So' (and Stanley's) are traditional, used to imply one thing follows another. The very common use that has formed during recent years is when someone is asked questions and starts most of their answers with `So'. As far as the UK is concerned, this all seemed to begin (I regret to say) with scientists. They were doing it well before the rest of the population, usually when asked questions by conference participants at the end of their lecture, or by the media. Thus if asked "Is Earth round or flat?" they would begin "So, the latest evidence suggests....". The word seemed to fulfil the same `thinking space' function as `Well' and `Now', but being unfamiliar it irritated many listeners. I don't know where the scientists picked up the habit; I would guess from US scientists...but where did they get it from, I wonder? The first time I heard anyone comment on its use was when the presenter of the Radio 4 `Inside Science' programme drew attention to it.

start with so
