Agreed, don't go the SEO route - it's not a long-term play.
This is a pretty strong SEO technique. You should be doing that already. You don't need to stick unrelated links there, just link back to your Twitter-themed site.
Note: I wouldn't use the noscript tag. I'd either have a div that was replaced via javascript or a small/light chunk of html below the javascript. Pretty good chance of noscript tags getting dinged by Google given how they are being used.
