Wow, quite nice to be honest. I think I better need to investigate If Go can really be used/replaced some of Java's platform or offerings right now.
For the mobile part, yes Java is the language behind Android, but if there would be a Mobile OS that can utilise Go then that would be a plus for the Go language .
Maybe Go needs some resources for newbies like me to check out and start developing out( I'd probably haven't checked if there are any), maybe you could list out some of the best things out there here.
I always like to read things from scratch , not soft copy but the hard one I'd probably check on this one.
