The tricky part is getting enough adoption for network effects to make it generally useful. So you need it to be useful to individual users before it has lots of users. Sort of like how Goodreads is useful for keeping track of books you've read/want to read, even if you never read the reviews or look at the lists that are a result of network effects.

The question is what features of a video aggregator would be useful to the individual? Watched list? Playlist management? URL shortening for sharing videos? Better UI? Export list to youtube-dl?
