The media/lit fan split is real, but if you only go to Swancon and/or Continuums, you probably think its not a big deal.

I'm told its much more notable if you to a thing like Supernova (which advertises itself as a 'pop culture expo' rather than a con). Writers are an afterthought they are a bit confused about. People told me about selling more in one hour at Conflux than in an average day at Supernova, even though Supernova is literally orders of magnitude bigger.
