First person to product wins, not first person to idea.
I started a blog post like a year ago that made a similar point to this article:
I like going to people's houses and being able to tell what kind of person they are from the films and albums and books on their shelves. Because, like the kind of nerd snob I am, there is a part of me that believes these things define who someone is (yes, I know it doesn't...technically). Ipods, Kindles, even Netflix ruin this.
My drafts folder is full of these. Ideas that I put down so that I'll remember to write something more elaborate later. Some are one sentence long (an applicable one, for example: "The internet just helps you realize more fully that all of your brilliant ideas have been thought of before."). Others are longer, but just never reached publishable quality (when did I even write these paragraphs about how I'm bored with the tired themes of African American literature? I don't remember this post attempt at all...).
But yeah, I was kind of upset/relieved to come across the Slate article because then I didn't feel like I'd have to finish the above draft. It's already been written about, so now I can just link and call my work done. (As if I was the first person to ever think it anyway...)
