Yeah...but..."connecting with" only applies sort of generally in YT case. You aren't really "connecting" with most of these people. YT comments are widely regarded as the lowest form of communication, and unless you form real relationships with other YT people like calling them and doing collab videos, it's a pretty shallow form of communication and connection. Confusing internet relationships for IRL relationships can lead to some pretty classic social disorders I think. It's pretty clear to everyone now that things like FB are curated lives, not real avenues of interaction. You're constructing and participating in a facsimile of life, not actual messy life with the same level of social risk and reward.
But that is a superficial view of it.
At one level comments are garbage yes but not entirely. I am a big yt follower and communicate directly with the host through comments often. The hosts of the luthier and performance related channels are there talking back and forth and it influences future videos. It's very much like a forum.
I also mentioned lots of other ways viewers connect. To generalize that comments are all noise and that all commenters are trolls is just not true all the time. There are idiots, as there are here but that doesn't have a big of an impact as you think.
If you talk to (or actually watch) any youtuber you will see their genuine thanks for the audience interaction and the overt influence it has on the channel. If you are not following any specifics channel by skipping around randomly, or just going on what you hear from others about yt, you are completely missing out.
- One guy builds guitars based entirely on user feedback
- countless amazing teachers give free performance tips to boost their private (online) lessons - see bass wizard in this thread
- my kids follow gamers and then get excited when they play with them in multi player servers by chance - they choose what to film based on user suggestions
- bands connect to audiences thru theur channels
- luthiers and tool makers expand and change their offerings soley based on yt viewership - see gelvin guitars, crimson guitars and many more
- some guys share a cover or do gear reviws - driven by user comments, see Constantine or MaxProud
- studio engineers share real tips for the home user for recording bass and everything else. see pensado, warren huart
All of these examples could not and would not exist without commenters. Replace that word with audiebce and I am sure you will see this in a completely new light.
