sister you have made good efforts but in some parts of the answers you fail to answer them properly but over all your efforts are great and I know it's really tough to don't know about a topic and then to search it from various sources and then to express the knowledge which is gained from different sources in your own words so you have tried to gain much knowledge but it was not enough

You have spoken very well about the changes and modifications in reward system and you also have been given its causes. You have perfectly talk about benefits of the convergent linear curve but unfortunately your understanding about curation types which are isolated curation and community curation are really very confusing and I don't think so you have delivered right concept here

I wish you a lot of success and good luck to you and I am hopeful about you that in future you would be able to do more research in depth and you would be able to provide such a good information as you have provided many times but unfortunately in this blog your research was lacking. Best wishes for you
