I know that and you know that. But we also have combined 10,000 posts on a Disney fan message board. We're not representative of the majority of WDW guests.
There's a new thread in this forum every day about someone taking their family to Disney for the first time. They're two weeks out and they're asking questions like "what rides are good?" or "we like to sleep until noon on vacation, is that okay?" or "what time is the bus from Animal Kingdom Lodge to Harry Potter World?" And for every person who registers on this site to ask basic questions, how many more are there out there who would never even think that a site like this exists, never mind that it's a borderline necessary resource to make the most of dining reservations, FastPass+, crowd management, itinerary planning, etc.?
