Buy, sell, and trade your baby stuff. That's the idea behind the newly launched site, WeeUsables.com, and it's a good idea considering a baby is born every seven seconds or so.
The home page greets with an adorable baby image with text informing you can register for free until June 15th. But it's only a couple of bucks a month after that, so it's still a good deal. After browsing the site for a few minutes, it has the feel of a Craigslist meets eBay hybrid. The categories are well thought out and sub-categories are numerous, so you're sure to find something you need, or a place to list something others may need. The site is easily navigated and you can search by city, state, or zip code so you can see if there is anything close to you. I've seen a bunch of classified ad sites, but I've never seen one that was really geared toward a specific niche like babies. I think that this site will be wildly popular.
