i dont think it really matters if a small youtube channel is giving out advice to othersmall channels, i think its really nice to see other people engaging with other people to help them also in the process, this community is good to reach out to other people that kinda need help in their channel, ive taken so much advice from smaller channels than me and they have helped me by a lot and i cant thank them enough but i try, i can only pass on the message to help others
i do agree on the engaging with their viewers/subs part, its not good to ignore people haha, reading and replying to comments is one of the best parts of doing youtube, talking about things, opinions, feelings and all that kinda stuff
