Dont misunderstand a vulnerability being present to everything being "hacked". Heartbleed was just a vulnerability that effects the majority of the internet and means most of it that uses common encryption protocols was vulnerable, but not necessarily that 100% of those that were vulnerable were hacked or taken advantage of or mined or whatever.
While it's a good idea to change passwords to things that matter and keep an eye on your bank statements etc, I don't support media-type panic spreading with sentences like "2/3 of the internet was hacked" because thats just silly.
