I'm guessing that I'll get a newsletter with videos, and "curators" will decide which are those videos? Will you subscribe to curators, or how that will work? can you suggest a video without being a curator?
I won't comment on the first or the third line of your reply, but I wonder, is a site that only gathers (or filters/ curates) content really useless?
I mean, there's 72 hours of video uploaded to Youtube every minute while the day remains around 24~ hours, there are so many things on the Internet that it only makes sense to create spaces where you can find stuff related to your interests selected by people you feel have the same tastes.
Just link to the videos / slideshares / whatevers.
