Hm. Hard to answer. Kinda depends what you consider friends. Im friendly with a few youtubers but maybe theres only 1 that i speak to regularly and would be happy to meet someday. Its nice though, we love to compare analytics and funny comments. And when you notice anything weird like your graphs, you can always check with your buddy to see if they got this too. Also sharing new features that one might have and the other doesnt.
We actually met through an official youtube online live chat and were the only two that stayed to chat more about it. So hes my youtuber friend perse, but you guys id consider friends too! Just i dont know you personally yet.
