They had 2 Pull Requests last month, closed 6 tickets and created 4 new tickets. To quote the "Pulse" section:
> Excluding merges, 2 authors have pushed 2 commits to master and 2 commits to all branches. On master, 4 files have changed and there have been 64 additions and 15 deletions.
This is not the kind of activity I'd expect in the project under active development. Compare to Emacs[1]:
> Excluding merges, 39 authors have pushed 227 commits to master and 260 commits to all branches. On master, 352 files have changed and there have been 6,143 additions and 3,732 deletions.
...and that's Emacs main repo, excluding all the development happening in plugins.
But well, that's actually not that important; what matters is that LightTable badly needs a serious refactoring, because reportedly there is just one person who actually understands the codebase (and it's Chris). Such refactoring is not going to happen, though, because people who actually could do it abandoned the project.
Perhaps it's not even a refactoring that's needed, but a rewrite. Even if using the same language - ClojureScript - the project would be supposedly written in a totally different way due to the changes in the ecosystem. Switching languages would require an immense amount of careful weighing of pros and cons, but it may be worth considering.
Still, this is not going to happen, the code and effort that went into LT are essentially wasted now, possibly with the exception of the learning experience for the authors.
I'm writing this much about it because I really hoped LT to be a modern incarnation of Emacs, as the latter was starting to show its age. Instead, however, LT is dead. On the other hand Emacs got embeddable xwidgets in the last release - which means that (in time, it's not very usable as-is) we will get the in-buffer, full web browser.
...and then abandoned it after getting me excited about a possible Emacs replacement...
