Thanks for the feedback - really helpful. I've been thinking about adding a poll feature (e.g. "Which of these dresses should I wear for a party tonight?"). Making that the main focus of the site is an interesting idea.
I'm trying to keep the homepage as free of clutter as possible but I do think this would add a bit of personality to the site (as opposed to the sterile, crowdsourced feel that you mentioned before). I'll have a think about a creative way to put this in.
Gotcha. How about this then: The users are putting in some nice personal words about each of their submissions. However, these extremely valuable words kind of appear as if they're coming from the vendor's site (watering them down, making them seem like catalog copy).
Suggestion: Put the words and user's avatar closer together. Move the vendor-link farther way.
This will emphasize the conversation. Perhaps even go crazy with a word bubble shape a la Twitter?
