  -  <p>Once you created a Factlink on a website, other people with the browser extension could see it. It didn’t modify the website directly, as that’s not possible, but it altered how the website is rendered using the browser extension. Thus we called Factlink “a layer over the web”.</p>

     <p>You could then post the Factlink to a channel, such as “Brain development”. Others who subscribed to that channel, such as experts or interested people, would see the Factlink on their activity feed. They could then give their opinion, add sources, and comment on the Factlink.</p>
   
  
positive.code:     <li>You could click a colour on the Factwheel to cast a vote, for whether you <span class="blog-fact-graph-agree">agree</span>, <span class="blog-fact-graph-disagree">disagree</span>, or are <span class="blog-fact-graph-unsure">unsure</span>.</li>
    </ol>
  
    <p>Initially, we started out with just voting. If you agreed, you clicked the green part, which would grow a little. And the number inside the circle would become larger. The same for the red and blue parts.</p>

    <p>What if someone adds nonsense <span class="blog-fact-graph-supporting"><i class="icon-plus-circled"></i> supporting evidence</span>, <span class="blog-fact-graph-f4">F4</span>: <span class="blog-fact-graph-factlink blog-fact-graph-f4">“The sky is blue.”</span> Someone can do this to falsely increase the credibility of <span class="blog-fact-graph-f1">F1</span>, especially if <span class="blog-fact-graph-f4">F4</span> itself is <span class="blog-fact-graph-agree">very credible</span>.</p>
  
    <p>We could have users reporting such invalid arguments, and have them removed by a moderator. But it might also be that evidence that looks like nonsense, is in fact relevant. It might just be that you don’t understand the subject matter well enough, or that it needs further explaining. Relevance isn’t binary &mdash; either relevant or irrelevant &mdash; but it’s a scale.</p>
  
    <p>In other words, we are not just interested in the credibility of Factlinks, but also in the credibility of relations between Factlinks. In our model, in the same way you can vote on the credibility of Factlinks, you can vote on the credibility of the relations between Factlinks: evidence. In an attempt to avoid confusion, we call this voting on relevance. You can <span class="blog-fact-graph-agree">agree</span> or <span class="blog-fact-graph-disagree">disagree</span> that evidence is relevant.</p>
