Today we released a new feature that suggests markets we think you should be participating in based on your historical trading behavior.
The list of questions appears on people's dashboards once they've logged in. We've been using this internally for the past few weeks and have tweaked the algorithm several times to improve relevancy. Based on our own increased trading activity we think others will find this lucrative as well. We've also provided a feedback mechanism for each recommendation, so if you don't like it, you can just click the "refresh" icon and a new recommendation will appear.
In the coming days as we continue to get feedback, I'm sure we'll tweak the algorithm further and we'll be adding the recommendations in more places. There may even come a day soon when the homepage of the marketplace is driven much more by your own activity and what has been determined to be relevant to you vs. only what the marketplace administrator thinks is important.
