Nobody asked my opinion, but I'll chime in. First, I don't see a problem with a new thread for every new Youtube video. I probably won't watch them (just being honest, I don't watch a lot of card videos on Youtube), but it alerts people you have new content. I'm already subscribed to you though, so one day I can binge watch a few if I want, just like I do with a couple other people who post card videos. If people have an issue with multiple posts for videos, then we should do the same for people that post "new ebay card" all the time. Make one thread and post it there. Fair is fair.
What I will say though is I've never been a believer of begging for subs on Youtube. On my videos (again not card related) I do put a subscribe button I think at the end of the video and other videos to check out, but I figure if the people watching enjoy the content, there isn't a need to ask them to subscribe. I admit I might change my tune if I ever get close to being monetized and it actually becomes a money making endeavor, but until then I won't.
I do agree on one thing though, it would be nice to have a little idea of what the video is of. Just posting a link does turn me off from checking it out, not just on videos, but any link posted on the forum. Knowing it is a PIF, or a pack opening, or mail day type video might entice people to check it out. Its true you might alienate people who don't want to see a certain type of video, but if they click enough links blindly not liking the content, they might never click any future links. Also and I'm not sure if you do it or not, but I really appreciate the people who post links that open in new tabs. It really irks me when people post a link and I click and it makes me leave the page. Its a minor gripe and I'm not sure if you do it, but its something that if I see enough of a member doing it, I probably won't click the link either (maybe others are like that too).
Other than that, it doesn't bother me seeing you post new forums for each new video, as it allows discussions on that video or on something else (like this one is doing). It also might inspire others to do the same and maybe build a network of vloggers on here.
