Well, by reading this whole 'community' introduction things, I have some concerns of my own. It's really good to hear the word 'community' on steemit. But in reality this would not work well. First of all, no one knows the infrastructure of community making and then managing. Secondly, by augementing this feature with tag feature, there would be a lot of confusion. People won't know what they are searching and what community would belong to which people.
The main concern is that people nowadays, on steemit, don't care about the content very well. They just needs upvotes, that's why a post with $30 upvote and shitty content can do well instead of a high quality content post with $1 upvote. Main power rest in the hands of Whales and they use it expertly among their favorite users or friends.
Instead of communities, steemit needs some inbuilt filters which can filter good content and make it to the hot or trending page. and flag the plaigrized content.
This protocols will soon be used in Peerity.io, a platform which would use Steemit infrastructure but with different style. In peerity, people would be rewarded for contribution their skills and quality content in communities. And they will be paid according to it. Peerity would focus on Communities growth rather than an individualism. That is the concept we need on steemit :) Making communites is easy but managing them and pull out good results from them is the real task.
Anyways thank you @surfyogi sir for sharing this community thread from steemit and adding your opinion.
