If they had any sort of system access they would have defaced the entire subdomain or the main site. So most likely, this is nothing to worry about. Your account data most likely still in safe hands.
Also considering that their Twitter and Facebook accounts were also compromised, your assumption that it was the blog itself that was compromised is a big one. I don't have any first hand knowledge on that though personally, I'm just saying.
So it looks like Skype doesn't host on its own server. It looks like this is wordpress.com but with custom domain?
curl http://blogs.skype.com -v

New to wpscan. When it says plugins found are these the vulnerable plugins wordpress.com running?

And I found the username 7 pretty interesting.... wonder if I am actually doing the ethical thing here :(

Seems a strange message to send to a country that spies on it's own citizens (and where apparently the citizens are unable to prevent their own government from doing it to them).
But I fully support the message here, I think that spying inside of consumer products is a sign of the abuse of power and monopoly.

How is MS more evil than anyone else?
EDIT: This really seems like an interesting question: _are_ there any advantages an attacker would have with skype's centralized system that they wouldn't with their previous p2p system? From what we've seen so far, I think the differences (from an attacker's perspective) are trivial.
Simply put, because of their market share, their evil has a bigger impact than other companies evil.
footnote: One is always completely free to decided if evil with more market share than other evils are more evil.

There are also tons of available security plugins & pretty extensive documentation on hardening a self-hosted install:

But hey, what do I know? ¯\_(ツ)_/¯ Only the tip of the iceberg. Some men believe.
Though also in my opinion even having a web-based file editor is pretty terrible...
WordPress isn't that insecure. A lot of third-party (i.e. written by inexperienced developers) plugins for it are, though.
