The people I like to follow on twitter most are those that are laser-focused on producing content related to one thing. Conan O'Brien, for example, almost exclusively tells jokes. I don't want to read his re-tweet of some fan's comment, for example. These make Twitter a lot less useful. A complement to your service would be to remove these less useful tweets from my feed, and just show in aggregate the links that were tweeted, as you currently do. I've spent very little time on Twitter; maybe this kind of service was first offered years ago.
Following what @georgespencer said, there's no strong brand here. Forget about the website and come up with a brand.
By the way, marketing yourselves to people that will pay you handsomely for professional services and then putting an ad for a $4.99 template at the bottom is a dumb idea.
I would focus on simplifying the steps a new visitor to the site takes. I found it confusing. For example, I got to the screen with the h1 text "Welcome", but at the top left was an animated arrow pointing to another Welcome button. Where am I supposed to go?
You have a lot of copyrighted works on your home page, like Spawn, The Little Mermaid, etc. Are these just ripoffs or are Disney, etc being compensated?
