Well, I see. The Like button isn't related in any way with FB. That's cool. I know SSL encryption take the server 15x more processing power on the server than on the client, but maybe you can add it as an optional element or even only for registered members (which I don't think will work, till port 443 is available for everyone).
And for the 30$ for the cert, just write an notification, or if you don't like it, write a PM to some members who will spend 5$ for a better PS3News (incl. me of course) via PayPal.
