Show HN: Wayin.com - Ask questions and "weigh in" on things you find online

We're a Denver, CO-based startup. This is the second release of our website—not just a re-skinning but a fairly radical re-invention of what we offer. Now that the service is live and has gained a small core community, we want to make it better. Any thoughts or criticisms from the knowledgable folks at HN would be much appreciated. Here are a few sample pages:
