This morning when I visited Sedo to search for new listings, I noticed a new banner under the header asking users to fill out a survey: “We need your Feedback! Help us to improve the search and thus your experience with answering a few questions.”
The survey is being hosted via Google Forms, and it is reportedly anonymous. I do not know if Sedo will be able to track participants who may be logged in to their Google account when they do a survey though.
