We are living in the Facebook/Twitter/Youtube generation. IMO with some hikers, the production of the video takes precedence over the hike. I've seen a few youtube videos where the hiker only does a 4-5 mile hike, and produces a 20-30 minute video...complete with dramatic background music. That said, nobody has to watch the videos if they dont' want to. I've been lucky so far, have not run into any hikers making movies or videos along the trail.
on my 2010 AT section hike from Springer to Damascus, I ran into Lint near Clingman's Dome... asked him if he was doing a Trail Journal on his thru hike, and he said no, he thought there were too many Trail Journals online, and with so many they just become noise. Now I get what he was saying ... Trail Journals can be fun to read, but some get a bit long in the tooth like a dear diary.
