I create my own videos for viewing, years afterwards, of areas I may never get the chance to go back to. For that reason, I include clips that were interesting to me, not necessarily for others.
If doing this for others to view, the best way to keep interest is to keep the overall video(s) short and only include the absolute best clips. Selection of music makes a difference too; do you want an upbeat, vibrate feel or a relaxing, laid back ambience or none and let nature do the talking? This has a huge effect on how a video is perceived. No pans, and really keep zooms to a minimum. If the clip is slightly out of focus, poor lighting, too many pans/zooms, not horizontal, etc. they'd be OK for my viewing pleasure but for others ... not so much.
I'll be viewing what you have as soon as I finish this post. To get an idea of my videos, you'll see that they are usually ... too long, sometimes out of focus, poor lighting, too many ... you get the idea - they are simply to capture memories for me.

If trying to do this for the viewing pleasure of others, I'd definitely have nothing over 3 minutes long, and only include the absolute best video clips and photos.
OK, now that I've viewed the blog post, I agree with what's been stated. I do want to add that using a tripod or monopod goes a long way to aid in better shots.
Again, chopping 10 hours of video down to 2 - 3 minutes for someone else to view is different from creating a 30 minute video for yourself. As an example, I just came back from a weekend trip in which I took over 100 photos. Out of those 100 photos, there's only 2 - 3 I would consider worthwhile to show to someone else.
