Well worth repeating. Most of us here can code a site up, some are exceptional at it. But even getting that initial press to get those first customers can be daunting.

That's one advantage I can see with something like YCombinator -- that initial traffic. It might not be much, but it's a few links from reputale blogs, some visitors and maybe even those first conversions. It's certainly no guarantee, but it is more than my first startup had.
