::If a subject doesn't have independent reliable sources it shouldn't be included. 
 ::It's not that is shouldn't be included, it is just an indication of notability. For one thing, the guideline on notability says that something may be included in an article even if it is not notable enough to have an article for itself. For another, if there is much discussion about something on the internet even if it has not been picked up by the more reliable press, it's difficult to say that it's not notable.
