I changed my skin to Timeless after seeing the ad.
It's mostly fine, but there are some issues. The most significant is perhaps this: The ULS control for changing the UI language is hidden under the user menu. It's not a thing that people often do once they settle on a language they want, but initially choosing the language for new users may become challenging.
Probably language selection should be part of the registration process. This not only overcomes this issue in case Timeless wins, but also, more importantly, makes even more users aware of the possibility to set their interface language. (And don’t be shy to tell all issues you found, so that Timeless will work as seamlessly as possible.)
