The quality of curation would be higher if people voted only on the content they were interested in, in preference to what happens now which is voting for content that they think will earn them STEEM. The difficulty to find posts that curators are interested in is becoming an issue with the very high volumes of posts. Functionality to "follow" certain headings - e.g. photography or travel, would enable curators to find what interests them as they log in and, as they are relative experts in those areas, would allow their knowledge to drive curation quality up. Also the possibility exists for people to become curation "experts" in certain fields due to the number and quality of their curation. Could this work?
