I somewhat disagree with HOO, a lot of what YouTube is about creating a community of viewers, and one of the ways you can do that, is with a call to action slate at the end of your videos, giving people options to watch your other videos, or other actions.
While I personally do not put end slates on my videos, as I don't think it would be the right fit for my channel/videos,
and some peoples end slates I do think are cheesy, I thought that your's was appropriate, and well done, and if people don't like it, they can click away from the video at that point.
