I think that is a great idea. It seems like that might be an idea for the "powers that be" in hubpages to look at. Maybe if they had a place where readers could request an article on a certain subject that was not already appropriately addressed. It could link into a similar database as what pops up when you try to ask a question....showing the hubs close to that topic and ask if none of them address the topic then allow them to place a request for the hubpage to be written. The same requests could then be placed on a forum where writers could sign up to write about it.
