Similar to the Archival Tools thread, make a guide for finding specific things easier. For example, YouTube has Hadzy for finding specific comments on a video, Twitter has an Advanced Search, 4chan has several archives, and so on. Maybe add some Google maps tips, specific tools for different browsers, sites for more legal-based stuff, etc. I think it's too often that people simply either know things about a person from experience or just stumble upon things rather than having the knowledge to find information easier.
