So what's the point? i judge LTT by its current code quality, not by its proponents shouting volume - and that quality is still quite poor at the moment. (and then there are the conceptual problems too, outlined numerous times) I have quoted specific example(s) for that in this thread. Furthermore, LTT does this: 246 files changed, 26207 insertions(+), 71 deletions(-) and this gives me the shivers, for all the reasons i outlined.
