I sometimes comment about and help others on the topic of travel on Reddit, often writing a lot of content. The incentive for me is that it&amp;#x27;s fun and intrinsically rewarding to help others do something that I find meaningful (which would fit into sibling commenter Gatsky&amp;#x27;s reason #2). So in a way it&amp;#x27;s kinda self-serving, but in a good way.&lt;p&gt;As for why authors don&amp;#x27;t just link to another webpage: I think it&amp;#x27;s because a) those pages often don&amp;#x27;t fit what is being asked, if it&amp;#x27;s more in-depth; b) the author might have a way to explain it that they want to use; or c) you might presume that writing your own content will get more upvotes.&lt;p&gt;Meta-funnily enough, in this thread we have both approaches: myself and others offering opinions, another guy linking to a Quora question.</text></comment>
