 I'm a pregnant hacker. Please review my side project.
I just had a baby myself (2 months ago) and would have LOVED this service during my pregnancy.  I too tried using Amazon, but it sucked.  So, I ended up going with Babies R Us, wasn't pleased with their service at all.Blogher would be a great source for you to find testers and get solid feedback from a group of mommies and mommies to be :).  Also, one thing that I liked about Amazon and Babies R US however, is they had list recommendations.  It may be a good idea for you to add some cool lists to you site such as "Top 10 Must Haves for Green Moms" or somethng like that.  I was clueless when registering and appreciated the guidance of the lists.I'll be sure to promote it here in Tokyo to the American moms!  Good luck with your pregnancy!
