Thanks for the suggestions, we'll look them up.
Also, we actually did do this for Bionic Dues. We did a "launch party" with both gaming sites and video channels, where they either posted an article/video on the game, or livestreamed it. We had about 35 participants ranging from minor to pretty significant (in terms of followings) -- but no one like TB (who had already mentioned the game during one of his PAX Prime wraps last year.
Yeah, I know all about TB, and his Youtube following, but one of the great things about Twitch.tv is the fact that a caster can interact with his chat. If you ever want to come by and say hi, and see how I'm doing, you can find me there honestly under the name ChthonicOne.
A number of smaller casters are moving to Hitbox however in protest of the chat delay, and other issues that are happening on the weekends. However all that is a consequence of how popular Twitch got for hosting game tournaments, especially on the weekends. They kinda needed to grow far faster than they were able to, so they're a victim of their own success. They're trying though, I can at least tell that.
I used to upload to Youtube as well under the same name, but after repeated false copyright strikes where even the owner of the copyright couldn't get it removed, I packed my bags and left. Further changes happened after that reconfirmed my decision to leave, like G+ integration.
That being said, I don't know what the future holds for either company. Youtube is still way too big to care about small fry like me. Twitch.tv is growing, but smaller casters get swept aside in changes designed to benefit their largest casters so they can make money and grow. Who knows when issues we face will clear up. Finally even Hitbox is a rehash service from a prior company that refused to pay their partners, then went out of business. Service might be good now, but who knows a year down the line. Me personally? I just like to chat with people while I play.
