It would be interesting, though, if the only planning tool people had was the official website.
I've often thought the same thing. Disney's website to begin with used to be notoriously terrible just to use (lots of crashing, timeouts and such) - the last few years since the last revamp have been better access-wise at least. But the fact that the information given is often so pithy and fantastical/hyperbolic that it's rather useless for informing folks on the things that really make a difference in a vacation experience.
Lou was speaking nothing but the truth. He does control a lot of Disney's marketing message. He's pretty much the highest profile blogger out there and if he starts turning that positivity into slightly more realistic based reporting, which would mean reporting the positive AND the negative, Disney all of a sudden has an unexpected problem in their marketing.
I think there are two things that need to be acknowledged there, though - one, that Mongello is usually so full of mouse droppings and political posturing (same difference) that it's very difficult to read anything he says and not assume there is some ulterior motive or at least an alternative motivation for him to do so.
Second, that what he said was rather out of touch and in the bubble at the same time with that statement. It would have been more accurate ten or even five years ago. Now, sites like that have been eclipsed by Twitter/Facebook. Sites like that are generally frequented by existing guests/fans. New guests aren't going to spend much time reading about things at sites like that anymore. It's just the ongoing development of how the Internet is used. Folks like him are way less important than they used to be.
My take is: he knew the gist of the story they wanted to tell, he gave them the sound bite they wanted, and he has his sights set higher than the online Disney community - he wants to use it as entry into larger journalistic endeavors. If so, he'll likely end up like Hill when after several attempts at being recognized and able to climb out to broader media reporting got his Huff Post "cred" (coincidentally, after that site had already lost theirs), which then fizzles out because he has no idea how to do anything but pander to pixie dusters and function in the "real" world. Hill is the perfect example of that - he burned his bridges with the fan communities jumping ship, and ended up irrelevant after he couldn't hack it in the bigger leagues.
