It's not worse when you append site:reddit.com to every single search but this is only a function of the fact that reddit can't figure out how to build their own search. Outside of maybe programming stuff where I'll still click on links, I don't think google has driven me organically to a new site in years.

Could you give some examples of search queries that would benefit from filtering by reddit?
(My own example: I've been looking for recommendations for a solid Linux laptop. A good result would be a list of reviews written from personal experience of owning such laptops. Reddit was useless for that.)
