When I first heard of the Mythology Area 51 proposal, I was very excited, and obviously I jumped in headfirst. However, I have been discouraged about the lack of influx of new users when we went public, and I have been thinking about why.
Think about the big sites: nearly all of them are helping people with practical, useful information in solving problems in their lives. However, no one has Mythology problems.
However, this is not necessarily a requirement for a good stack. Code golf certainly isn't about helping people with their off-internet problems, and the history beta seems to be doing just fine. However, if not going to be a site that has practical information, we have to focus on the other things that make people go to a stack - fun!
tl;dr what can we do to make Mythology.SE more fun?
