^And that right there is one of the reasons why I'm such an optimist about being on Youtube...
Yes, there is the risk that you'll be discovered. But I'll admit that posting the videos, and the compliments and support that you get from other people, feels AMAZING! And unlike pictures, where you can just say things like "well, it was a good angle, and in that pose I look like my true gender, but if they could see the real me..." because with Youtube videos, they are seeing ALL of you... voice, motions, hand gestures, how you carry yourself, all of it. So when you receive compliments, you REALLY feel like you've done something right. Posting my first couple of videos was a HUGE confidence boost in my presentation, and I still feel great every time someone comments on the videos.
