I like babynames. Not sure about .io
If I had a bunch of bady names I could list them on the site . . . or have a cool blog where people submitted baby names along with cute baby pictures??!!
Having said that, seems like a niche market . . . Lets see if my estimation skills are in line with other namepros! Ill go reg fee up to $99.
I can see this as a nice tertiary website for say huggies diapers, whoever sells pacifiers, life insurance for kids perhaps, etc. I personally see that as a route to go, but like I always say, I am not a domainer, I do not think like you . . . in my signature!
