There are highly rewarded accounts on Hive that often act as interpreters of information from other posts, but often these accounts are making very useful contributions, I think.

I've seen many posters that reword popular posts in a different way that can often be more accessible to a larger audience. Such posters often expand on the information, show potential linkages to information from othe rplaces, and speculate on possible outcomes. To me that goes far beyond mere replication.
