Great trailer, if you're a fan of these films or even these types of films I'd imagine you're hyped for this.
Also I'd like to let you in on a secret. The reason I post trailers like this isn't to try to drive traffic to this site. I typically don't even share these posts on Twitter or Facebook. I primarily do it with films Dad might like. Then I call him and say, "Check my site out, the new Avengers trailer is there." It's an easy way for me to share these with him so that he doesn't have to go hunting down the right one. That's the deal if you ever wondered.
It is also a nice opportunity to make the site look more up to date even if the posting has dropped off. That's really the only benefit to the site itself, new content on the main page.
