Computer networking pioneer Robert Metcalfe developed a popular (and disputed) concept in the 1990's which became known as "Metcalfe's Law", which says that the value of a network grows exponentially with the number of participants.

Applying this concept to PaleoHacks, this site should become ever-more valuable as it grows. Yet I can't help but notice a recent spike in the amount of divisiveness, invective, closed questions, etc. Also, most of the "easy" and "obvious" paleo questions have already been asked and answered. In my view, this has led questioners into areas that are more esoteric, repetitive, localized or contentious (such as politics and public policy).

My question is whether PaleoHacks will continue to scale well, and what can we members do to keep it vital, fresh and friendly?

Great question! Maybe moderation becomes more important at this point, with respect to already-answered questions. And somehow gently nudging newbies to search before asking--not only on paleohacks, but on the wide world of paleo sites. Personally, I gravitate towards reading questions that apply to a large number of people and science-y questions, and veer away from "I have this individualized problem...what am I doing wrong" questions. – Kamal Mar 18 2011 at 1:04

There's a lot of paleohackers. It's tough to tell who to listen to and who to ignore, especially as rep points do not perfectly correlate with knowledge. (e.g. Kurt Harris is on here once in a blue moon) – Kamal Mar 18 2011 at 1:26

I still like the "individualized problem" questions, even if I've seen a lot of the problems before. I guess I just like hearing people's stories. – Paul Mar 18 2011 at 1:44

One of my faults is that I am too tolerant of quasi-trolls. I need to take a firmer hand with PH and start ripping out the drama-queens (or drama-kings for that matter) right away. – Patrik Mar 18 2011 at 1:54

This is a great question.

Well one thing I want to mention -- maybe I'm dodging your question for the moment -- is that Paleohacks would still serve a great purpose even if it somehow, theoretically, lost all interest to longtime users. I told a friend about the website once, because she was learning about the "lifestyle." She came back to me a week later and told me: "Paleohacks is amazing. Every question I could have possibly been interested in is there. Omega-3? Type it in, there it is. Weight loss? Type it in, there it is. Green beans? Type it in, there it is." And so on. (Although maybe I shouldn't be making the green beans joke, since that was before my time.)

But perhaps I'm coming around to your question, because this does suggest at least one thing we could work on more: fine-tuning the answers to the basic questions, making them better and better. Because for every one registered user with a screen name and a presence in the conversation, there might be two more who are just reading along. A lot of those are beginners. How about making things better for them?

One problem we encounter here is that when old threads are refreshed with new answers or new edits, relatively few users look at them. It's always more exciting to see a new question. So there's not all that much incentive to go back and edit your answers; even if it had nothing to do with reputation, there would still be the issue of views. Why do that work if no one is going to look at it?

This leads me to believe that the "repetitiveness" of near-duplicate questions is not an entirely bad thing. It's almost like we want slight variations on the same theme, just like we want to watch the same romantic comedy over and over again, but with different actors and actresses. Patrik anyhow endorses the idea in the FAQ:

Please look around to see if your question has already been asked (and maybe even answered!) before you ask. If you end up asking a question that has been asked before, that is OK and deliberately allowed. Other users will hopefully edit in links to related or similar questions to help future visitors find their way.

But if that doesn't satisfy, if the re-working of old plotlines is not enough for us, then how about this: things do change in the paleo world. Think about all that has happened just in the last year or so: the fall of insulin, the rise of the potato, skepticism about fish oil, the re-discovery of choline -- not nearly as earth-shattering as world affairs, to be sure, but for those of us who dedicate a big chunk of our free time to thinking about this stuff it's enough to keep things at least somewhat fresh.

Maybe the site will slow down a little bit. But I don't think things should come to a stop. These two things -- refining our answers to old questions, and dealing with the occasional new ones -- are definitely enough to keep us going. These aren't startling new ideas from me, I admit, but I'm more the synthesizing type than the creative type anyway. So that's how I see things.

(Note: My own personal project is to try to keep learning about human metabolism. Because even if a lot of the basics are well-known and can be learned with biochemistry textbooks, a lot of it is still unknown. And even if it is known, even if it's out there somewhere, there's still the challenge of putting it together. I think a lot of this work happens in various places on Paleohacks, even if that's not everyone's cup of tea -- and I certainly don't think it should be. Sorry about the long answer, but, you know, in for a penny in for a pound.)

So you're going to make a paleo-centric metabolism website? Sweet! – Kamal Mar 18 2011 at 1:46
Actually, I thought this was going to be a branch of your new website. – Paul Mar 18 2011 at 1:52
Touche. I have an idea though, and already bought the domain name. Semi-promotional paleohacks question coming next week... – Kamal Mar 18 2011 at 2:02

I think slight variations on old threads = awesome. Simply repeating old threads in a manner that indicates that no effort went into the search bar = not awesome. – JJ Mar 18 2011 at 4:38

@Jae and Paul, agree. I would like to see questioners link to the old threads, and perhaps explain why the old answers were not quite what they were looking for. – Ed Mar 18 2011 at 13:07

It's funny that you mention this, because I never really thought about it before earlier today. I'm reading a book called Crowdsourcing by Jeff Howe. Today I read a section that says that crowds with a similar knowledge base tend to do one of two things: A) they divide into factions that pit some ideas against others, or B) they slowly develop a consensus. Jeff's argument is that either of these actions serves to decrease the diversity of the crowd (and so decrease its value as a problem-solving entity). He seems to feel that part of the value of internet communities is to bring together people from disparate backgrounds who can increase the diversity of a knowledge base and therefore increase the number of innovative and efficient solutions to problems.

I haven't been around this site long enough to get an idea of the phenomena you're describing, but I wonder whether the plethora of information that is now available on the Paleo diet and lifestyle makes the community more homogeneous and less diverse. Perhaps people are all coming at this site with information from the same five or six books and blogs, and so therefore the perceived value of the community is not growing at the exponential rate you might otherwise predict. I’ll just have to spend more time here and see what kind of value I can discern before I can really make a determination.

Thanks Vandy, I'll have a look at Jeff Howe. Here's a link to his website: crowdsourcing.typepad.com – Ed Mar 18 2011 at 1:12
