Ask HN - Review my startup - A way for bloggers to connect with other bloggers

The site is called Post Amigos - http://www.postamigos.com. I think there is a lot of value in guest posting and I have not seen an easy way for bloggers to connect with other bloggers through guest posting. My plan is to make it a hub for all these types of activities.

My "competition" is myblogguest.com and bloggerlinkup.com. Would love to get feedback from the community.
