There's a lot of talk on HN about the value of marketing. Beyond its relevance to my hobby of fencing in general, I enjoyed this article for its depiction of these two clever guys who are going with a spontaneous idea and seeing where it takes them. There are obvious and myriad differences, but their attitude feels very "bootstrap" / "startup"-ish to me. (Particularly the parts about primarily studying or working while they trained, and still overtaking well-funded "professionals.")
