My sentiments exactly (on not revealing my face, although I will at some point).
I think you are spot on with the 7 day rule, but not to worry, when I have more 'subscribers' I will just use the script for a post instead.
I actually find talking harder to be as concise as typing so another reason for the racoon. I could make a script, record, rerecord making expresions etc. It was very time consuming so not very good when it takes 1-2 weeks to write and record/rerecord.
It does sound like something you might enjoy playing with though, especially if you have the skill to do it on the fly. If you have access to Steam (the games distributer online) and some form of pc camera, download 'facerig' as you get it for free. I paid for more stuff but I dont think you have to unless you are earning a fairly large monthly fee from using it (I just wanted to play with some different faces that I ultimately did not use).
