I think this is difficult to answer and do, due to the decentralized nature of Hive. A lot of people would like to keep it that way to preserve this decentralization. But if I were to answer it, I think the Witnesses are the closest we have to this. We can maybe have them as a collective serve as the leader. If you want a single person, then it can be Arcange who is the current top voted Witness, or they can nominate one among themselves.

I do think that we need to do better as a blockchain in getting our name out there and getting more users. I don't know if getting a singular leader will help solve that, but I think making better use of the Hive Fund on better projects can be a start.
