Ask HN: What ideas is YC now mostly looking for? Has it changed over the years?

[pouzy]

I've been discussing with a few people and we were wondering in what way has the YC portfolio changed over the years.

Is there a shift from consumer-facing possible moonshots (Airbnb, etc.) to more "world problem solving" ideas, like genetics, big data, renewable energies... ?

YC has a specific request for startups page[1]. What they have been looking for changed over the past few years.
