&gt; Why mailing lists are still quite massively popular in 2015?..<p>IRC is still an underused tool in my opinion. The ability to just talk about one issue in a Mail List and keep track of the communication is great. I can&#x27;t think of another tool that manages communication as well as a mail list (Forums are just not as good in communication notifications like a mail list.)<p>P.S. I still hate Mail List and don&#x27;t use them anymore but nothing does it as well right now.
