For anyone who happens to be reading and whom I haven't spammed about this already:
This isn't paranoia folks, this is the future. Everything you say should be encrypted at every layer, unless you what it to be completely public. If you have a wifi router, you should have WPA2 turned on (not WPA, and certainly not WEP). Every personal transaction should be over SSL. Your ssh keys should have pass phrases on them (which is different than a password, and isn't sent over the wire). Know your data, know everything that touches it. Prophylactics are the sign of a good netizen.
 Sorry about the redundant email, I just scraped all the gmail addys from my address book
