If your site is protected by CloudFlare (like HN is), you are automatically protected from this vulnerability (see: http://blog.cloudflare.com/staying-ahead-of-openssl-vulnerab...).

You are protected now. But you were not before, so if any attacker figured this out before the public disclosure then you have [possibly] already been attacked and compromised.

Not entirely correct, as the blog post states:
> We fixed this vulnerability last week before it was made public.
Although there's still the other 103 weeks this was vulnerable to worry about.

This is perhaps somewhat misleading. It's possible that this bug was being actively exploited before now, so you should change your keys even if you use a CDN (all the majors have already fixed this as far as I'm aware).

Perhaps Cloudfare should note that the "up to 64kB" isn't entirely correct.
>>There is no total of 64 kilobytes limitation to the attack, that limit applies only to a single heartbeat. Attacker can either keep reconnecting or during an active TLS connection keep requesting arbitrary number of 64 kilobyte chunks of memory content until enough secrets are revealed.
