Lesson Five: Instead of relying on your memory or stacks of sticky notes, use a password manager.
I like Roboform.com, which now works with multiple browsers including Firefox and Chrome. But remember, you still need to create a strong password for Roboform to remember. Don't want to buy a program? You can get some, but not all of the benefits, by using features built into most browsers that can automatically fill in passwords you have saved.
Lesson Six: Be wary of public PCs.
When using a public computer in a hotel or cafe, be absolutely certain that you've logged off and closed the browser or at least the tab linked to a sensitive site.
There's a lesson here for Gawker staffers as well. Be a little humble. Next time you start to pick on a site or a person who has done something dumb, take a look in the mirror before you post.
