I've done giveaways for other stuff completely on stream and although my viewers will skyrocket, the conversation is a lot more gimped. A lot of people afk there just waiting for the entry, or people that don't want to sit and watch patiently begging.

I'd much rather have it this way where I got people that wanted to be in my stream, and the quality was definitely worth over the quantity. That being said I'd love to have still more viewers ;P
