Is this like the
Twitter feed readers that take
what should be a blog post on an
external site and stitch them back
into something readable, instead of
a blog post in 40 parts?
There are plenty of sites that focus on long form videos and it might make sense to put long form videos there, if one wants long form video content.
Youtube. It's pretty much just Youtube. They are the only player with meaningful market share. Even Facebook video is most effective at only 20-40 seconds.
I would welcome any competition to Youtube, even if it means TikTok expanding.
BTW, I skip all multi-part videos unless there is a good reason for being multipart. Most are trying to game the system.
But then I thought about the fact that a lot of significant developements were "just <something else> with a slightly different presentation."
Some creators do this, but not enough. Besides with 3 minute videos, this shouldn't be a problem anymore.
