I often wonder why web-startups need business co-founders. At least in HN circles, that doesn't seem to be a widespread view. The general opinion seems to be that if you're motivated and reasonably intelligent, you can work out the business stuff as you go along, as long as you can build a viable product. That's not to say they're useless. If you need to or would like to raise money, or developing a prototype is extremely expensive and you need to get sales early, having a person dedicated to that aspect is probably a good thing.
