I'm neutral on the scroll bars themselves - but what seems weird is they allow inconsistent size, and don't scroll much - regardless of the code size, if I get scroll bars they only scroll a few characters worth.
As far the ads - I can't complain. Webmaster keeps the server updated really well - someone's gotta pay for that, and the site's always very responsive.
edit: I'm betting the scroll bars are a browser-thing, anyway
