I've seen a few people set up topics here for them. As long as you don't create a topic for every single video people don't seem to mind. If you have a topic dedicated to sharing your videos it's also a great way to get comments from the community.

Don't? There's already millions of people who think that for some reason their personality is cool enough to warrant watching them play video games. The last thing we need is more.
I don't think it's really about that though. I don't think I have a better personality than anybody else, I just have fun making the videos and it's sweet to see a bunch of views and likes on them. It's a hobby and some people like watching em ya know?
