I re-designed the interface for Zizim back in May, and the original plan way to implement the new design into the existing PHP build. I got to a stage where it was nearly finished, but I made the decision to re-build the backend using Ruby on Rails because the end-result would be a clean codebase and a strong foundation for the API which I will be releasing at the same time.
The build is nearing completion, and will be released over the next week or two.
All of the previously shortened URL’s and aliases will be retained. Hooray!
