Safe passwords and the hacking of Gawker Media

Gawker Media has been hacked:
If you’re worried about whether your Gawker user password  has been compromised or not, the company’s Lifehacker blog has published an FAQ on the issue. Essentially, if you logged in to comment on Gawker, Gizmodo, Jalopnik, Jezebel, Kotaku, Lifehacker, Deadspin, io9, or Fleshbot you need to change the password for both your Gawker account and anywhere else you use that password.
The problem is that some people use the same password for all of their accounts. The hackers have used this to hijack Twitter accounts. Lesson: Use a different password for every account you have. Some kind of pattern derived from the site name is probably the way to go if you don’t want your brain to explode.
