I learned a few knots and even now when I buy a new pair of shoes I consult the site to see what lacing style would suit the shoe and my foot. (since different styles put different tension on the wearers foot).
I have to say, I'm happy it exists, it enriched my life in such a subtle way, this is the kind of content that the internet was made for in my opinion.
Orthogonal to shoes and such, I find that I end up searching for recommendations for products on reddit as opposed to a store or review engine. I prefer to know what enthusiasts think rather than a bunch of randoms who have voted based on a star system.
Are there are sites that just list products and have only a single recommendation for each category? "This is _the_ boot to buy if you are looking for cold weather boots. It's a good combination of warm, waterproof and stylish." That's basically what I was after and exactly what reddit delivered after some searching through relevant subreddits.
