The Apollo Marketplace has seen a great deal of success. This is no accident. However, there is a feature which could increase its efficacy, which is a 'wanted' section within the marketplace.
I, on a few occasions, have found myself with great resources but with nobody to benefit from them. If the Marketplace allowed people to post not only what they want to sell, but also what they want to buy, the community would benefit in ways it has not been able to yet.
Newcomers would likely find comfort in this added feature to the Marketplace, as it would allow users to more efficiently identify what the Marketplace offers.
