That compound question: "Will this disable HTTPS on our website completely?" <-- That to me appears to be just downright silly.
"What clients rely on SSLv3 still, should be be concerned about supporting them?" That seems too broad, with the exception of mentioning IE 6. The real answer is "Depends." What apps rely on your SSL web app?
I dunno, that question just seemed like zero effort was put into it. The edit didn't even help it much.
