I see he has a list of his most favorite esoteric and arcane tools juxtaposed irrationally with a list of somewhat more popular ones.
The real problem with this list is that he makes absolutely no attempt to rationalize any of the judgments he makes. He simply says that x is much better than y; therefore everyone should use x. Presumably there is this underlying expectation that anyone who finds this page will immediately think, "Oh, shit, he's so right, these things I have been using for many years without problems, and which I am very comfortable with, really are shitty, so I had better use all of these other programs instead." Of course no one is going to think that. Among the people who actually give a shit about whatever programs they are using (which, for any given program, is already likely to be a small fraction of those who use it), the vast majority of them like whatever they are using. Why? Because if they didn't like it, they would find something else. Naturally the ones who don't give a shit what they're using are also not going to bother switching to something else even with a good reason, so lists such as this are even more lost on these people.
I really don't care what this guy writes. I use what I like, and a lot of the stuff I use - and like - are listed in his "Harmful" column. This categorization seems entirely irrational to me, and without anything resembling justifications for his labeling, I have no reason to switch away from tools I am comfortable with, just so that I can spend large amounts of time learning new tools I am unfamiliar with. This is compounded by the fact that these alternative tools are, on the whole, unlikely to exist on whatever system I am using at the time.
Therefore, I believe that cat-v.org should be categorized under "Harmful." See what I just did? I gave my reasoning, and then I stated my opinion. You're certainly allowed to agree or disagree with me, but you'll at least know how I came to that conclusion, and heck, maybe I even convinced someone to change their opinion. And what's even better, if you feel differently, you can tell specifically what points you disagree with. It's rational discourse, which is something that tends to be completely lost on, curiously, the very sort of people who make these sorts of websites claiming that some particular thing is either terrible or fantastic.
