A lot of people are interested in the project, would like to contribute to it, and would be happy to take over where you left off. However, this is difficult to do due to lack of documentation and any support from yourself.
You can read the experiences of one person trying to contribute here (https://groups.google.com/forum/#!topic/light-table-discussi...) and here (https://github.com/JonyEpsilon/gorilla-repl/issues/132).
Since you're not going to be actively working on the project, why not involve the community find individuals or an organization that would continue developing and maintaining it.
Surely, this is not too much to ask and it would be a responsible way to transition from the project.
