&quot;Why mailing lists are still quite massively popular in 2015?..&quot;<p>Because (your email client) is always going to be much, much faster and easier to navigate than &quot;some dudes cute forum setup&quot;.<p>Replying to and managing conversations is much easier when you can do it with one or two <i>keystrokes</i> rather than mousey-mousing ten clicks all over the place (and oh their ad tracking js is stalling out again...)<p>I maintain that all web forums should have a mailing list interface so that you can use the forum without using the web at all ... but I suppose that breaks their revenue model ...
