In addition to completely re-doing the header and modifying the look of the site, we've added full-on user accounts now, rather than the anything-goes system we had in place before. Visitors can still vote on anything, but only registered users can submit content. We're hoping this will increase the quality of the content a bit, while also allowing us to provide more functionality to the users who do sign up. Some if those added features include email controls, a scoring system for users, and a commenting system for each scenario. As the site scales, the commenting will allow for discussion of merits or the scenarios and words. Finally, we've implemented a new emailing system to give users a "daily digest" of what's changed for them on the site. Before, you'd receive an email anytime something happened on your username - that sucked if your submission became popular. Now, everything is compiled into one email, which gets sent once per day, max.
There are lots of other, smaller changes as well, all geared toward increasing retention and sharing, but those outlined above are the major changes.
