I do personally have an interest in live streaming, walking around and ride videos because I don't get to WDW often. I don't know what the parks look like other than google earth views and examining park maps after 6 years has passed. The vlog stuff holds a lot of appeal to me personally and that's only a recent last few years desire for me.
I do watch and have no desire to just listen. I really enjoy seeing them but that's probably because I'm an auditory and visual learner so I enjoy seeing their faces, I enjoy seeing the powerpoint slides they have up or to show shirts they are wearing, etc. But that is me personally.
All that being said I get my fix elsewhere. I watch Tim Tracker, I watch This Orlando Life, I watch every now and then random other vloggers and I watch the DIS and most of their videos (WDW Unplugged, Universal Unplugged, Dining reviews, majority of Best and Worst, random videos, really enjoyed 7 in 7 to see resorts I wouldn't otherwise see, etc).
So I get the other poster's point and I get your point and decide that one can have both in this World (pun intended) but not necessarily from one source. Would I love more on ride videos from the DIS team? Absolutely (just watched a few days ago archive footage of Ryno and Craig riding Barnstormer OMG I couldn't stop laughing) but I appreciate what they do now and am totally fine going elsewhere in addition to the DIS to get my whole fix.
