Darcs was technically interesting, and also a joy to use. However it suffered from the exponential merge problem, which I think is still not fully resolved.

Once you hit that all the theory and nicities went out of the window.

The merge complexity in darcs 2 really hasn't been an issue in my usage. As I understand it, it is resolved for darcs 3, but maybe I misunderstood that from skimming what was going on. (The new theory seems to be different to Pijul's, and perhaps inferior.) I'd be happy with either as a joy to use.

I/we definitely hit it in real life, sufficiently often that it became obvious we needed to move to another solution.

At the time it was probably CVS to darcs, then it became darcs -> hg, and giving in to the inevitable it became git.

That's kind of the point of Pijul

Yeah if it can be solved then that's great news. But having tried "everything" I think it would be a tough sell to switch at this point.

The momentum is clearly behind git, and has been for quite some time. None of the more recent contenders have ever become popular (bzr, fossil), though of course they have their advocates.

Having the code be reworked in-private, for a long time, too doesn't make it seem like it is ready to become usable in the short-term.
