I'm fairly new to the Stack Exchange network, and I really like the Q&A format used here, which is very clear to read and to use.
I started exploring all the sites, and I found there's a Code Golf site (http://codegolf.stackexchange.com), but it doesn't seem to be a Q&A site, but rather a contest site, which seems to go against what the Stack Exchange sites represent.
So, why does this site exist in the network? Wouldn't it be more suitable in a different kind of site?
Please note that I do enjoy the site (I read the challenges every day although I've never sent an answer), but I'm curious about the issue.
