Is Steam's "New & Trending" and "Popular Upcoming" based on your history?

As far as I know, it's not based on your history. I see lots of trash there too, which is why I don't really pay any attention to it anymore.

Why are wishlists so important to indie devs? (w/ Chris Zukowski)

It's based on amount of wishlist's a game has. If a Dev has a game in EA, and that said game has reaches a threshold of about 7k wishlists but ideally 10k, using the pareto principle or 80/20 rule, this will translate to roughly ~ 20% of the game being bought in an ideal situation.
If a game also goes out of EA with a discount, those who have added a EA game to their wishlist, will in turn will generate an email about a potential sale being sent and steam in turn will try to promote the games.

The only thing that will be affected that is based on your browsing history is your Discovery Queue, which is how Devs gain potential Wishlists.
