YouTube Comments: Imagine you were successful YouTuber...
How would you manage many many comments (not all need answering but maybe actually there is 1000 "wow that's great" and 100 more are a good comment / worth interaction / healthy as eco-system interaction...
Experts I've spoken to *always* have this problem - they want to sort things but interface or sheer mass overwhelms them.
This is not for Sir Richard Stallman... but it would help him and all experts because when in right mode or filters they are EXCELLENT :)
Even when 5 good people naturally gravitate towards you it can break you life! (overwhelm / be bad timing or something / many things... I'm not speaking for everyone but just imagine your were famous!)
Getting incoming mails or comment or what is important I think to answer - almost all or deal with and it's been a problem for long time (1000's of great comment on YouTube for example and such mixed level of learning)
For this scenario you can imagine all comments are genuine and so this doesn't have to be spam related and from 1000 there is 100 good things to reply... the focus here is quality mainly).
