Maybe I live on the other side of the web. Because I don't get how linking to authority website can make one's article better. Anyone? Please explain.
It doesn't necessarily make an article better, other than academic reasons like citing your sources, or recommending further reading.
But, for an SEO reason, there is one. Can't remember if I've ever seen this as part of the official Google SEO guide or not, but I think the hypothesis behind it is that Google doesn't like people hoarding their link juice. That they prefer people link to related articles where there is more information on the topic.
So they reward websites that do this at some level. It's a very minor ranking factor at best. But it is also very possible that this is an SEO myth that's been propagated over the years.
As for me, I will link to other websites as I see fit, as that's the entire reason the web was created in the first place: to link between online documents with hypertext. As an added philosophy in the age of Google, we link to documents that we think provide good value to others.
As an added note, the disavow tool wasn't meant for this purpose. If something like this takes off, I can only imagine it'll be pulled from Webmaster Tools in short order for widespread abuse. Then what are people supposed to do in situations where black hats actually are trying to employ a negative SEO campaign? Its use for Goog TOS violations notwithstanding.
