Well I kinda see yahtzee's point, Particularly with the rather intentionally trollish, meaningless and destructive most internet comments are.
I suppose that a big part of problems come from the fact that a lot of human communication is pretty unnecesary and redundant. But this is not limited for internet, it is simply accentuated by anonymity, its like Pub / Bar / Club casual conversations, rarely does anyone get involved in very significant interactions, and most of the times the communication is limited to very superficial popular knowledge niceties that could very well be fully ignored.
It seems a bit of a problem of CONTEXT more than content, for example, Shouts and general stupid behaviour seem fine if you are in a crowd at a stadium, watching some sport, but that wouldn't really be fine anywhere else.
Likewise, We all know that in general, youtube is not the place to find stimulating intelligent conversation... (just trying to maintain a conversation in Youtube seems nearly impossible). But even if we didn't know, after an initial learning period, we learn to expect the way things work within that context.
Here's where I find a problem though. It seems rather arrogant to dismiss all opinions as completely "twatty". I feel it is a bit rich for "internet personalities" to play that card. It's a pretty relativistic observation, I know, but for someone else everyone is potentially an opinionated twat on the internet. The only real difference is the coverage and the number of followers. The truth is that It's very difficult (and sometimes pointless) to verify people's credentials online, but that doesn't immediately make comments ( and feedback as a whole ) useless or unworthy.
Clearly Yahtzee feels entitled to consider other twats from his ideological podium, but the truth is that his particular skill is in the presentation of opinions in an entertaining way, and not on the side of very provable or scientific analysis and observation. So although it is surely very entertaining, he shouldn't assume every comment that he dislikes is just the work of an entitled twat that isn't respecting -him-.
Sure, a different experience or perspective can contradict his opinion or diminish his experience, in such a way that is as potentially offensive as Yahtzee's own rhetoric. But who can really say how valuable any person's opinion or input is universally? It is a moot subjective appreciative point.
Can Yahtzee scoff and call anyone contradicting him a twat? It's kind of what makes him "famous". But in time anyone else is very much entitled to find his opinion just as stupid. Didn't he get to where he is by kind of being an opinionated twat? Some people could even enjoy comments! Scary concept, I know.
So I guess this is an ouroboros of twatyness, Yahtzee is an internet commentator, saying comments are stupid and we are commenting on the dumbness of his comment.
In the end, with the type of interactions we find nowadays, we have to learn to discriminate what information IS in fact VALUABLE to us, and is WORTH the effort. And learn that whatever we say, someone will have a problem with it, even if we simply cant understand the reasoning behind it. Its probably the biggest communicational challenge we have in the near future, discerning what information we actually want.
You, Mr. Yahtzee are rapidly becoming decreasingly relevant.
