I would definitely change something related to DHF, it's the topic of the moment, we would need to greatly improve the way it is applied, think about alternatives or improvements, because lately the impression is that a lot of "money" is being used and we are not getting a return that matches it.
I think that although peakd badges, for example, define some hive users with certain achievements, I think we could bring this natively to the hive. For example, we could create visible ways (staying on the profile) to define that a user is a great addition to Hive, that is, that they contribute a lot. I think more ways to reward those who really strive to grow here, help people, and trust Hive are very welcome. Just as we could flag someone who has committed some abuse, leaving a warning or a flag for a few days, it would also be nice if this flagging ended and the person had a second chance to continue creating content.
Finally, perhaps we could create mechanisms to improve marketing. I think we really need that, but exactly what that improvement would be should be a good brainstorming session to get us there.
