Don't be put off. I average about 1 moaner to every 100 positive messages I get. I ignore every moaner, not interested. And the positive messages I get are amazing, many from disabled viewers who are unable to get out. One person not long ago thanked me because I put the GC code on the screen and they loved to look at Google earth to see where I was.
So go Vlog and enjoy yourself! What's the worse that can happen? Your log gets deleted? So what!
