So, it is called glogger or peerviewr???

Maybe it is only for my case. I always think that the domain of the site should be the name of the site too.

Yes I am sorry I just put this up and used an existing domain I had I will clean that up soon. Basically it is like a cross between google groups and a blog. So you can share things and cross post to specific groups. Rather than a blog where only one person makes things public lots of people can blog/post/share things publicly and privately. Also you can share lots of things links videos files posts etc and it can interpret them and render correctly. As I said it is like a group blog.

Need a descriptive catchphrase under your logo. I like how you have lots of whitespace but it feels empty, need to add more content, especially on the right side.

It's not immediately apparent how your app is different from a blog...

And I agree that you should choose a single brand for your site, either Glogger or PeerViewr. See here: http://blog.weatherby.net/2009/02/yes-master.html

Why would say someone who has a Wordpress blog, for example, post those links at your site when they automatically get published in Wordpress, Technorati etc? I am trying to understand what would drive users to your site and I can't think of a reason for now. Is there something I am missing?
