I will come watch.
If the timing is such that I'm available, I'll watch.
I'll offer answers too if I can figure out how to do so.
I would enjoy watching you explain things about bitcoins, you write such great post.
I'm a LOT better at written communication that verbal communication.
With written communication, I can take as much time as I need to think through what I want to say, and I can edit and adjust it as needed before it is submitted. I can also break apart the questions that are asked and answer them each individually without interruption.
Verbal communication requires almost instant responses that "sum up" the entire idea being expressed. When I try to do that I tend to ramble on and repeat myself multiple times restating in hopes of clarifying (and as a result simply making it more difficult to follow what I'm trying to say).
Also, I'm decently skilled at searching for answers to questions. Most of the information people are wanting already exists, they just need someone to look it up for them and phrase it in a form that matches their question. I don't have all this stuff memorized and available at the tip of my tongue. I just look it up each time I need any facts or details. That's a LOT harder to do in the middle of a verbal conversation.
