It would actually probably only take a day to make a responsive layout for this site. I could probably come up with some responsive CSS later this week.
EDIT: Fuck it, 30 minutes of effort with stylish, try this CSS out:
@media (max-width:767px) {
#wrapper {
padding:0;
}
#sidebar-left, #sidebar-right, .header-banner {
display: none;
}
html, body, #wrapper, #content, #action-container, #thread-header, #thread-container, #action-container, #post-form-block, .header, .header-nav-container-inner, .header-nav, .footer, .reg-activation-notice, .footer-inner {
width:100%;
min-width:auto;
margin:0;
}
.bau, div#content > div:first-child {
margin:0;padding:0;max-width: 100%; overflow:hidden;
}
#thread-container {
border: 0;
}
.post {
border: 1px solid #b4b4b4;
margin-bottom: 20px;
}
.footer-inner-left, .footer-inner-right {
float: none;
text-align: center;
}
}
Requesting $100 for my consulting Kappa. I don't have ads so I can't actually see if they look good/bad (should be bad because they're suppose to be 758px or something). If you want to make it better, increase the size of the +frag/-frag buttons + font size. Still this should be vastly better.
EDIT2: Boulder, not sure how your app works but you should look into javascript injection. You can literally just add a <style> element with my code and it will have all the functionality but a different look.
