I don't remember if we did it, but we certainly talked about focused advertising for the Continuums.

So if our guests were a DW author, and an SF writer, when advertising them we would make the DW author the first and most prominent name when advertising in the DW and media community, and make the SF author more prominent when advertising to the more heavily lit-based community.

Three out of four Continuums had feedback forms, which really helped us shape our direction and find out what people wanted... and it also helped us to ignore the whingers :)
