Indeed, we tend to stay away from the 'delegation for curation' of any kind. We floated the idea a while back but it's highly frowned upon on Hive. We do manually curate all content using the '#Slothbuzz' tag with boosted $Slothbuzz rewards through Sloth.Buzz website. So we give a free boosted curation, no delegation needed.

Unfortunately, most users prefer a 'boosted' Hive curation instead of the Hive-engine token, but we strive to continue highlighting the best content on Hive! Maybe we'll look into some form of delegation service again soon. We'd need to really consider the overall Hive impact with such a move. Thanks for the suggestion.
