I have to say that ingame many of the local channels in big towns are not new friendly. In smaller towns though I often seen people getting help or talking about stuff like runes, weapons etc. I tend to help people who don't spam. On the other hand, I turn off local occasionally if I am trying to talk with guild mates or the team I am on.
One of the resources that is fairly new is pressing f10 - this brings up the official wiki.
