For people who use up/down arrow or pgup/pgdown keys to scroll down the page (which is pretty much all laptop users), this focus stealing misfeature would frustrate them to no end.
I won't go back to any site that does this.
Steady on, soldier. I just asked a question.
Judging from the up-votes it seems this resonates with a lot of people.
To me you haven't made any case at all why others should have to suffer so you can have auto-focus on Amazon when your needs are already met elsewhere.
"!amazon thingamabob" (or just "!a thingamabob").
Way more convenient than going to the homepage and worrying about search auto-focus.
"a foo" to search on amazon, "g foo" google, "i foo" imdb, "m foo" google maps, "w foo" wikipedia, "u foo" urbandictionary, etc... I have more but they are not public sites.
Sounds like the two could complement each other, like aliases and completion in a shell.
I have "w" for wikipedia, "y" for youtube, "gm" for google maps, etc...
This is THE feature of Chrome that I use constantly every day. It saves 5-10 seconds on each search you do every day. It adds up.
Isn't a better strategy to optimize for the common use-case?
I don't think it makes sense on Amazon. A typical amazon user may browse around and explore outside of search. Maybe most of the time they will search, but there are no doubt other use cases like using the fancy nav. It's even possible that they want to encourage user's the browse around a bit instead of finding what they want and leaving right away.
