Mass, world-wide attention: Vlogging.
No pre-write required: Blogging.
Visually appealing: Vlogging.
Easy edits later: Blogging.
More creative control: Vlogging.
Fewer haters: Blogging.
I mean, there are definite extremes, in that people could have a widely popular blog, in that they would gain an array of haters, and the world-wide attention that vlogging, on a site such as YouTube, could present. These generalizations are meant for the majority of users who don't make it big, or as big as you can be on the InterWebs.
Having said all of this, I will continue to post vlogs, stupid short films, and my own senseless ramblings via video form.
