Earlier quoted context omitted.
I hear you. I think the one thing that makes this different is that I'm not going after the universal wishlist market, just the baby registry market. When you go to create a baby registry you're not like "oh, i need a wishlist of items for the baby". I'm just starting to market this with people in the pregnancy/baby space, and so far they seem to think this is a totally original idea made just for them.
I agree with at least one thing bdclimber14 seems to be implying. babyli.st is a 'cute' domain name, but I think it is an extremely poor choice for domain names you want people to remember. How are you supposed to pronounce that to someone? Baby - lee - dot - ess - tee ? (I know, that's terrible -- I can't come up with something better). I still think it is true, for better or for worse, that for businesses the best…
Also, natgordon - great site. If it was useful outside of the US I'd point several friends to it immediately.
