I really like the idea of FiveSecondTest – it’s a lightweight, free webapp for gathering user feedback on your site designs, particularly suited to people who have zero budget and little time for user research.
The original version had fairly basic functionality, and this is something they are trying to address with their new beta. They are looking for UX people to try it out and give feedback. With your input, fivesecondtest has the potential to become something really valuable. Go try it out.
