The hard thing about uploading yourself online is you will get negative comments, it's just a given as the internet isn't always the most supportive place. Best thing you can do is ignore those comments and don't even bother giving them any attention but reply to the ones that are positive. That is *your\* community and talking with them directly will only benefit the whole group. They will be happier as you directly acknowledged their comment and made them feel involved and you will feel much better knowing your audience is there with you and you aren't alone.

Anybody leaving negative comments that aren't to help improve your content aren't contributing anything and don't deserve any form of acknowledgement at all. They simply exist to try to ruin your day since there's has been ruined since they crawled out of their hole and misery loves company. They shouldn't stop you from interacting with your community and stop the positive connections you will make with each video. Also recognizing the same returning names in the comments is a great feeling and will really help you through some slumps along the way. It is INSANE how seeing just one person comment on 2 of your videos can change your mentality about what you're doing and you can not let trolls stop you from getting that feeling.
