There are so many other (perhaps similar) platforms out there... if you don't provide a set of features, some screenshots or anything that tells me more about Blarb I am not giving you my email.

It's not clear if this is a social network, a blog or a reddit like thing. It's not clear who I am sharing with, what the UI looks like, or anything that sets this apart from other services. All the landing page shows me is the features this thing does not have.
