I question the use of the word better. Discourse and SHK (stone hearth kingdom) are two different styles of forums.
Discourse is a loose formatted forum, with posts sorted into a few different categories. posts are easy to spring up, and when they do are presented to every one in a twitter like fashion. This is great for talking to people about the game, getting to know who is who in the zoo, and throwing up some ideas for the game. not so great for collecting information into one place but meh.
SHK follows a more typical forum format, with a lot more structure, allowing people to share information in longer posts as well as get a lot of separate information into open neat tidy area. However due to the structure of the forum, quick small posts of “what do you guys think of this” are not as easy to post due to the forum feeling a bit to formal.
Both forum types have its up’s and downs, but seeing as the game is still in development, my 2 cents is that the informal, quick posting of ideas is a bit more suitable. Besides, we still have the wiki for posting all the large bits of information.
