Surely soon-to-be-outdated steps to take before recording a screencast (or presenting using a computer):

    1. clear all browser caches

    2. clear all saved form data

      • saves potential embarassment

      • also hides the fact that I've done a run-through already

    3. clear all browser history? Sometimes might be useful.

      • reason to clear history: links appear as not visited

    4. turn off all unnecessary browser extensions

      • people will ask you what those icons are

      • people will try to figure out how you work

    5. turn off all apps that notify via Growl and whatnot

      • even better: turn off Growl

    6. close all unnecessary applications

    7. pre-load all necessary websites in tabs or windows

Maybe this should fit under the "Perfect" section.
