> What makes a social network a social network? I'd boil it down to something that offers 2 way communication instead of read-only (I'm not including clicking on a link [GET request] to get to a different page as part of 2 way communication, although technically it is). If it has a commenting system, voting system, or any other way for a user to be able to change/alter the information that is displayed on the site/platform to other users, I'd call that a social network. News sites used to be more like news papers. You could only read the article. Then they just about all added Disqus/commenting systems, which turned them into more social networks. A typical weather type app is not a social network. It only shows the weather.
