The last item cited, typography, could hardly be seen as a design 'trend' itself. That's like saying a designer's use of colour or negative space are regarded as stylistically in vogue today but may have been less prevalent or even nonexistent in use at points in the past. Typography is a core element of design. Period. It's not something that falls in and out of favor as a trend.

While this is true, I think you're missing the point. Typography as a primary graphic (al-la-street art / grafitti) is actually a distinct notion. Seperate from idea from notion of typography as a digital variant of calligrophy, etc. The latter has always been an element of publishing/desktop publishing and design (steve jobs, etc). The former has not.

Regardless, typography as a primary graphic element——and to be clear, we are talking about the Web——is not really a trend in my mind.
