[fr] J'avoue une préférence marquée pour les conversations linéaires plutôt que hierarchiques (en arbre). Les conversations linéaires génèrent peut-être moins de commentaires, mais elles ont un rapport signal/bruit plus favorable, n'encourageant pas le hors-sujet. Elles sont plus faciles à suivre et me semblent plus adaptées aux blogs.
So, now that [Going Solo Lausanne is behind me](http://going-solo.net/2008/05/17/going-solo-lausanne-was-a-hit/) and I can come back to a slightly more sane pace of life (and blogging here, hopefully), I’m starting to read blogs again, a little. Don’t hold your breath too long though, contrary to popular belief, I’ve never been much of a blog-reader.
One topic I’ve read about a bit, and which is of particular interest for me, is blog commenting. Aside from the fascinating topic (I’m not kidding) of blog comment ownership, which I touched upon myself more than 18 months ago, there is the age-old debate: threaded vs. non-threaded comments.
On the backdrop of my [break-up with coComment](http://climbtothestars.org/archives/2008/04/19/more-on-cocomment-advertising/) (impending, in the process, fresh) and their post about [commenter’s rights](http://blog.disqus.net/2008/05/30/a-commenters-rights/), I’ve taken a closer look at [Disqus](http://disqus.com). It looks promising, it does some stuff I like, but also stuff I really don’t like, like the dreaded threaded comments.
So, here’s an attempt to try to explain why I think that threaded comments in a blog context are not necessarily a good thing — although popular wisdom would have that they are “better” than normal, flat, conversations.
I did a little research to see if I could find anything solid to back up my claims (if anyone knows of [proper research](http://twitter.com/stephtara/statuses/825117034) on these issues, let me know), but I didn’t find anything really solid. So, I’ll just have to try to make this logical enough that it can be convincing.
**The appeal of threaded conversations**
Threaded conversations are as old as the internet itself. Usenet, e-mail discussion list archives. So, they’re nothing new, and have been around a while.
When blogs started including comments — oh yes, there were blogs way before there were comments, and the commenting script I used on this blog was for many years a popular destination — so, when blog started including comments, those comments were not threaded (in the sense that they allowed hierarchy in the comments, or branching off, or a tree-like view).
For many years, all I saw on blogs was linear conversations, as opposed to threaded, tree-like conversations. Most forum software also functions like that.
Then, of course, with some regularity, I’ve heard people asking for plugins to make the conversations on their blogs “threaded”. And I wondered. Why the attraction to hierarchical conversations?
When we have a conversation, be it with a single other person, or around a big table, it flows in one direction: the direction of time. There is before, and there is after. One might say “you said something 10 minutes ago that I’d like to answer” — and we’re quite capable of following this kind of conversation. We do it every day.
If we chat, be it on IRC or on IM, or any other kind of chatroom, we know that there are often multiple intertwined conversations going on at the same time. With a bit of practice, it doesn’t bother us too much. But the important point remains: the conversation is ordered chronologically.
So, be it offline or online, most of the conversations we have are time-ordered.
I think the appeal of threaded hierarchical conversations lies in the fact that they seem more “orderly” than one long stream of posts, ordered not necessarily by the logic of the conversation topic, but by the flow of time in which it takes place. It’s hierarchical. It’s organized. It’s neat, mathematical, logical. Algorithmic. Computer-friendly.
But is it brain-friendly?
Human beings do not think like computers. Though some human beings who spend lots of time programming or give excessive importance to logico-mathematical thinking might like approaching problems and the rest of life in a binary way, that is simply not how most people function. (Literary backdrop for this paragraph: [A Perfect Mess](http://www.aperfectmess.com/).)
I think people who like threaded conversations like them because they have a higher order of organisation than non-threaded conversations. And better organised should be… better.
You won’t be surprised that I disagree with this. A good conversation online, for me, is one that can be easily followed, caught up with, and participated in. In that respect, a linear suite of comments is much easier to read or catch up with than a huge tree. When it comes to participating, the linear conversation offers only one option: add a comment at the end. In the tree, you first have to decide where in the tree you’re going to post. (Literary backdrop for this paragraph: [The Paradox of Choice](http://www.amazon.com/Paradox-Choice-Why-More-Less/dp/0060005696/).)
**How the format impacts the conversation**
Another way to tackle this is to examine what impact hierarchical and linear comment threads have on the conversations they host.
Hierarchical – Threaded:
– off-topic comments branch off into separate conversations
– overall, more comments
– lots of parallel conversations
– conversation stays reasonably focused
– less comments
– limited number of parallel conversations
I personally do not think that “more comments = better”. On a blog post, I like to see the conversation stay reasonably focused on the initial topic. For that reason, I think that linear comments are best on a blog.
**More conversation is not always better**
Of course, there are always parallel conversations going on. On Twitter, on FriendFeed, in IM windows I’ll never know about. As a blogger, I would like a way to point to these conversations from my post, so that a person reading could then have access easily to all the public conversations going on about what they read. [Conversation fragmentation](http://climbtothestars.org/archives/2008/04/27/diigo-i-think-i-like-the-idea-bonus-content-conversation-fragmentation/) is not something we’re going to get rid of, but we can try to minimize it.
Increasingly, our problem is becoming one of signal-to-noise ratio and chatter. These are subjective notions. My signal is somebody else’s noise, and vice versa. I’m happy that there is chatter and small talk in the world and online (it’s a big part of human interaction and what relationships can be made of), also about what I write. But on my blog, I’d like to keep the chatter somewhat down, even if that means my “number of comments per post” or “conversational index” is not high. I’d rather have less conversation here, and give it a chance to be more interesting and accessible to outsiders, than huge 50+ comment threads that nobody is going to read besides the hardcore die-hard social media types.
**More reading and listening**
You’ll find some of the links I found on del.icio.us. If you’re into videos, the topic was raised about 6 months ago on Seesmic. Here’s what I had to say at the time:
– [threading encourages the conversation to go all over the place](http://seesmic.com/v/n03MEC9S1U)
– [threading changes the nature of discussion](http://seesmic.com/v/aDDiGJWdw5)
– [conversations are chronological](http://seesmic.com/v/PWt1wmig5I)
I’ve also dug up a few quotes I found in some old discussions on MeFi. They’re in my Tumblr, but as Tumblr tumbles along, I’m reproducing them here:
> If you’re trying to build community, it is clear that linear, non-threaded discussions are superior. There is a good body of research on this – it’s not new, it’s not a novel idea. For tech support stuff, hierarchical tree structures are better, in general.
> One of the arguments for adding any feature that is designed to hide noise is that it gives it a permanent home. When Slashdot added moderation and auto-hiding to their threads, they gave the -1 NATALIE PORTMAN’S BOOBS brigade a permanent home on the site.
> I checked out digg’s new setup earlier this week and 75% of all the comments were complaining about mod points. I don’t know if that’s an improvement.
> This place is like a pub.
> One does not have threaded conversations in a pub.
