We're on a roughly bi-weekly release cycle, but I missed the previous one, so some of these enhancements have been up for a couple weeks.
We've been spending a lot of time on usability items that became clear the moment people started using the live system. You may not notice them individually, but overall, the number of times you think, "Hmm, I wish it worked just a bit differently" should be going down. We've got more to do in that department.
The most visible change is our new home page. We're using a news item model but grouping the items by type to make them easier to digest. We've also added a summary of your key statistics on the right. The goal is to provide an at-a-glance way to keep track of all your TurnTo activity.
We've been working on the instructional text throughout the site as we learn what's intuitive for users and what not. The one you're sure to notice is the big welcome message on the home page with advice on getting started.
And we added a Delete Account button on the profile page. We hope this won't get used much, but we think it's good web citizenship to make it easy for people to leave if they want to.
We're eager for your feedback. Please let us know.
