I don't think social media aggregators are useful but curating content from an open social network is
how to search right information in all these social networks? improper push will lead to information silos and it will not change without aggregators.
I believe that the content should be original and not duplicate the content of another social network, another author
Aggregation can be automated or truly human experienced. What do you have in mind and why is it human? Also, what are the incentives? How do you build appropriate incentives around curation?
Having a system for community curation would be dope. Like you subscribe to a community vs. one person. Could potentially use tokens etc for such things.
I totally agree curating content from an open social network is useful but at the same time we need to take note of a few things. One goos example is when we curate contents from an open social network, we need to respect the original creator and avoid any copyright issue.
