Sedo and Afternic are the two most prominent domain marketplaces. Its where many who know nothing or very little about the domain market go to look for a purchase.
These sites should be displaying names on the front page imo. Taking up the majority of the homepage with recent sales, auctions and a place for people to promote their names for a fee.
When someone goes there and sees a vibrant aftermarket, it should give a better representation of the value of domain names.
Sedo does have a spot at the bottom of the page but its not good enough. A feature listing on the home page costs $39 for 30 days. The spot is a rotating spot. There are only five spots. There should be 25, think of the additional money for Sedo, and the better exposure for the seller.
Afternic shows no domains on their front page. This is just not the right move imo.
Increase the awareness of the names. Make it easier for end users to see more names right away.
