Personally I think collab channels were great at first, until collab like O2L and the Seven Girls version came along I which that was when everybody wanted to strive to be them. But that's pretty much YouTube. I hAve been in a collab and it is very fun until differences causes the entire group to part ways. I live collabs, don't get me wrong, but it is hard to find ones that are willing to stick together when one thing goes wrong.
