The news story making the rounds about Facebook the past few days indicates they’re working on a kind of “dislike” button.
The problem with the Facebook “like” button is the same problem Google has with Google+ and their “+1” button: it doesn’t tell you anything meaningful.
Voting on Reddit doesn’t really convey much meaning, either.
Stack Overflow tries to address this with its up/down voting and being able to see the gestalt votes as a ratio (if your rep is high enough (an admittedly low bar, but still a bar, and an aspect of the gamification of Stack Overflow)). But that doesn’t really cut it, either.
The problem with online “voting” (or “liking”, or “plussing”, etc) is that it is a dimensionless data point.
Does getting 300 “likes” on a post make it “good”? Does it reflect on its quality in any way? How about getting nearly 400 upvotes (and only a handful of downvotes) on a question about MySQL (along with 100+ “favorites”) mean the question is good? Does it show something is popular? Are people clicking the vote mechanism out of peer pressure, because they actually agree, or because they think it needs more visibility? Or something else entirely?
Dimensionless data that gets used as if it has meaning is a problem – one of many problems of social media and web sites in general.
Of course, you will object, quality is a potentially-subjective term – what does “quality” mean, exactly, when talking about a post, website, question, etc? Is it how well-written it is? Is it how long? How funny? How sad?
Take this question I asked on Stack Overflow, “CSS – how to trim text output?” It’s clearly-written, was answered excellently in 2 minutes, and is a “real” problem I had. Yet in the 4.5 years since asking, it’s only gotten 2 votes total (both “up”, but still only two).
Reddit has upvotes and downvotes – and your comment/post score is merely the sum of the ups and downs; below a certain [relative] threshold, you won’t see content unless you ask for it.
One of the biggest problems with all of these systems is that the “score” doesn’t actually tell you anything. An atheist subreddit, for example, will tend to downvote-into-oblivion comments that are theistic in nature (especially from Christians). Quora‘s voting system is highly untransparent – downvotes don’t really seem to mean much, and upvotes are pretty much just for show.
This derives from the fact that these sites use dimensionless data and try to give it a value or meaning outside of what it really is – a number.
What should be shown is the total number of “votes” a given post has gotten – positive negative, reshare, etc – but never combined. A ratio could be displayed, but the sum of the votes is a poor plan.
Facebook, Google+, and others should offer various voting options – “up”, “down”, “disagree”, “agree”, “share”, and possibly others – some of which may be mutually-exclusive (you cannot upvote and downvote the same thing), but you might downvote something you agree with (or upvote something you disagree with) just because of how it is written/presented, etc.
And the total of each type of click should be shown – show me 10,000 people disagreed with what I said, 15,000 agreed; 20,000 upvoted, and 30,000 downvoted; 12,000 reshared it (with, or without, comment).
Using voting as a means of hiding things (and trying to prevent others from seeing them) can be somewhat akin to online bullying – revenge voting has its problems; as does blindly upvoting anything a particular person says/does. Which is why assigning (and then displaying) dimensionless data anything more than a count is dangerous.
Comments on ““like” problems: social ‘voting’ is a bad idea”
Voting does have *some* usefulness – in StackOverflow, it’s used to help order the answers (the same philosophy was used in Slashdot comments). Voting on questions seems more like an afterthought, but it still has a little value. The biggest issue with the voting setup on things like Reddit and StackOverflow is the “one number to rule them all” it creates. Voting is at least a sign of “I think this is good” – but that’s very dependent on the community maintaining a clear sense of what deserves an up or down vote.
“Like”/”+1″/”Favorite” is different -they’re indicative of *nothing*. In theory it communicates ” liked this thing” but it’s so low-friction that it’s almost a read receipt for posts. Not to mention the glorious schadenfreude that is people clicking “like” on obviously tragic posts – the “like” link has lost all meaning – but because the like count “one number to rule them all” everything (like post visibility) is based on that meaningless count.
It’s looking like the real solution to this is that interact with something on a social network/social site should involve more friction. You lose data points, but the people who push through can probably offer a more meaningful signal than just clicking a button in a web app.
There is a modicum of usefulness for voting in some contexts, I agree – but the way it is implemented pretty much everywhere you look, it’s meaningless.
Removing the “votability” option, and instead get folks to comment/share, could be god, too
Oh I agree, comments, reposts, even full-form responses (e.g. blog posts in response to other blog posts) are much better signals of engagement than “liking”, “+1ing”, “favoriting”, etc.
Makes me think that should be the only way to interact with a post
