I really like discord. This seems like a good move, there is plenty of information locked inside discord at the moment. For instance I'm part of the Wooting keyboard discord and there's a lot info there on problem solving, customizing, etc. There are tons of other discords like this, especially for games. I personally have a dota2 guild discord, but none of these are likely to be searchable as mostly they are private (often with public invite links somewhere) and don't have many users (I think mines at 180ish).
