Welcome on Steem for better life community.
Its good to hear that you selected this community from lot of communities, to explore more. I am not from this community, and I am not able to welcome you. But those who can they already done this.
I just want to tell you, that you are doing amazing work sir. I want to invite you to explore more communities, so I can see you in communities where I work.
Maybe my content can be lucky to get your eye on it.

I feel that if general users don't enrich this platform with their valuable contributions then only developing its infrastructure will be sheer valuless. Again, if the development team of this platform is very weak and ineffective, users will turn away from it

You are very right here. I am pretty sure, there is no community for video creators on the platform. I just want to ask you to visit my steemit promotional video posts
And let me know if this idea works. If I create a community for video creators, and bring them all on the one community (platform) for them. Maybe I am able to this. Or maybe I am not.
I am telling this, because when we try to make a collaboration of two platforms, like YouTube and Steemit we can go far better. Many YouTubers will easily use steemit and YouTube. Just they have to show their creativity to post their videos in specific community. So we can collect many of content creators, as well as other creators will take interest in creating videos. And posts related to videos.
