A great read, it touches the heart of implementation issues of all sphinxen. And its criticism on my implementation a right straight to the point.
I felt very relieved when the current maintainer attack what I did in the past. (Some features I did were rather stupid.) This shows that Sphinx is still alive and will still be alive.
