Thanks for the link, Milo. The system is mainly used for commercial organisations and would-be pollsters. As you say, it doesn't seem to be relevant on PPRuNe because:
1 - No-one is aiming for a commercially useful outcome, and
2 - We can work the ranking out for ourselves.
And thanks for your lack of response, LGB.
SunnyJohn, thank you for your replies.
Maybe I wasn't clear, if so, sorry about that.
On many other forums and social networks, where certain topics are discussed, there are ways for users to express whether they found a post useful, or harmful. Some places, like FB, does not (yet) allow for a dislike/downvote function, but many other sites do.
In either case, any kind of up- OR downvoting would enable filtering, sorting and other ways to show the content.
If there was a function like that, those of us with other things to do than spend all day on the internet would have a chance to benefit from subjects that are bombed with thousands of replies, by getting to the point, the important posts.
Not only that, but users will have a chance to display their opinion toward a certain post, just like you can cheer or boo at a gathering to show your support - or the opposite!
Lack of response ... well, I am going back to the real world, if I don't reply here in the near future, it's because I am busy NOT being on PPRuNe
Milo, thank you for your suggestion, I will see if that is of any use
