<p>Eventually the activity of making new questions and answers decreases (a lot of questions have simply already been asked, some even several times) and the activity should be replaced by curating the answers and questions.</p>
<h3>Community Wiki</h3>
<p>This can be done in a Wikipedia style. Instead of many multiple questions and answers, which creates a chaotic database where only a layer of votes creates an overview, we could also strive for having less posts, which are edited by multiple people instead of each writing their own separate two cents of contribution.</p>
<p>It is a bit confusing on the platform here.</p>
<ul>
<li><p>On the one hand there is an individualistic style of writing posts where individuals each write their own posts and the contributions are being mixed in some sort of ranking of posts by means of votes. Editing by others is only done to a limited extent. There is some sort of ownership of the post because votes are being 'collected' by the person that wrote the original post. Not only are the posts being ranked but also the people that write those posts.</p>
</li>
<li><p>On the other hand there is in principle no objection to editing another person's post. Anybody can edit a question and/or answer and you do not even need an account for this. In some cases this is explicitly promoted by turning posts into wikis.</p>
</li>
</ul>
<p>Possibly we could turn older posts with many votes into community wikis. The voting, to measure popularity, has become deprecated for such questions and answers. Improvements should be made to the existing questions and answers, rather than adding a new answer.</p>
<p>A major problem with this approach is that many old posts are of high quality and moving towards a community style of answers may actually reduce the overall quality. In addition it will remove the individual style of answers and turn it into <a href="https://en.m.wikipedia.org/wiki/Design_by_committee" rel="nofollow noreferrer">writing-by-committee</a> with little variation. Stackexchange is not a Wikipedia.</p>
