One reason could be if you wished there was good resource on a topic.
For example, if you wanted to convince someone that they should develop for iOS instead of android, you could start an article on Listry titled "Reasons to develop for iOS". Then add a few reasons of your own to the article, and then other Listry users could add their reasons, everyone would vote on the best reasons, and then in the end you would have a good resource of all the best reasons to develop for iOS.
A reputation system would definitely be a good thing to have too. I was thinking about creating one, but decided to launch early, and then improve the site over time.
