I remember seeing a comment you made asking for people to check your channel out on one of SuperJeenius's videos. You really shouldn't do that. While it seems it has given you some more views and subscribers, seeing those kind of comments annoy a lot of people. Quite honestly, when I saw the comment, I simply ignored it. That comment was marked as spam, by the way.
Really, you should just try getting more active in the let's play community. Try to talk with some of your favorite let's players in their comments section of their videos, their Twitter, and their Facebook. They might just notice you. Talking to those guys may be intimidating, so if you don't feel up to it right now, then you can also look into finding other let's players around your size. Make connections.
