Random datapoint: My e-mail was one that got hit in this hack. 15 minutes ago my Twitter and Gmail both just locked me out. I was able to set new passwords via mobile verification, but that was pretty spooky and clearly someone is going after the people who got exposed here.
Even if you're not, my email address is getting spammed with password reset attempts for Battle.net, LinkedIn, Facebook, Amazon, one of my banks, Twitter, etc.
Granted, all had different passwords, but people are taking full advantage of this information being made public.
Personally I'm not as worried about Gnosis or 4channers doing anything particularly malicious with the data -- that's not their goal. Their goal is to publish it so other people do malicious things with the data, with all the resulting animosity being directed to Gawker.
