Re: Bad post, starting with the title
We have no way of knowing this, since the charts are complied based on how many issues comic stores order rather then how many of those issues are actually sold.
Here in Chicago area, the audience seems to be doing alright. Over the past three years, we had three new stores open in Chicago, and a local comic book store chain (Graham Crackers) opened two new locations. Outside Chicago proper, one store did close, but it had more to do with the fact that the shopping strip where it was located has been dying a slow painful death ever since it's anchor store fell on hard times a couple of years back.
Modern comic books have their problems, but, as I said elsewhere in the comments section, I just don't think declining sales is one of them.
