The introduction of Google's latest search feature "Preferences" where you get to add sites whose results you prefer to be a source of your search results seems to reflect their move to "Trust" ranking.
"The preferred sites feature lets you set your Google Web Search preferences so that your search results match your unique tastes and needs. Fill in the sites you rely on the most, and results from your preferred sites will show up more often when they're relevant to your search query," Google explains.
You can add and remove sites you do or don't want factored into what you are looking for. Sounds like you are giving Google solid information to move from a link based algorithm to a 'trust based' one. How things change in the future could be interesting.
Factor in William Flaiz's recent article about the relevancy of rankings and the idea is not a stretch.
