Wouldn't that sort of stuff go into the "Pulp" board? Or is Pulp just up the 70s? You still see posts about 7TV turn up here every now and then rather than that board for instance.
Its an issue of stuff being too niche as well, where there may be too little posts to warrant opening a new sub. However, there's already certain boards here which don't see much traffic. Frankly even this sub's not a rave of activity every day and its one of the larger ones (at least from my own perspective).
