On: But why can't I send people their passwords?

[mreiland]

I re-use passwords, but only for things I don't care about.

Not everything is critical, if someone gets into my HN account, for example, I'm not too fussed about it. It sucks, but whatever.

If someone gets into my bank account... different story.

It isn't that people re-use passwords that's the issue, it's that they do it for shit that actually matters.
