I wouldn't consider myself a normal user, so I don't know. "Like, comment, and subscribe" also was once a popular thing to say at the end of videos too. I'm sure for some individuals this would be beneficial to reinforce. For some it had no impact. For others (myself included) it would be mocked. I guess the question is, does less than five seconds of text at the end of a video (which some people may not even see) hurt more than it could potentially help? My search terms don't seem to find such research, if it was done. My assumption, however, is that there are plenty of people out there that will do it, and might look at the comments to see what others have discussed. And some just have to comment on everything.
