Personal websites for Youtubers don't really make sense unless they have some kind of format that can't be handled via videos, playlists, or their descriptions.

The only ones I've seen for Youtubers are cooking channels, where the description format is very poor for recipes.

I only stopped checking the websites of a couple YouTube channels I follow, because they stopped updating them reliably. I preferred that to checking on YouTube, because sometimes it takes me a bit to find a simple chronological list of videos from a channel, while the sites were just that, right on the front page.
