I have been on Hive for two months now, and based on little information I got from reading some blogs, Hive is barely 3-4 months old. It's amazing how well it has faired considering how "young" the project is.
So far, there are few DApps running on the blockchain, with the commonest or the pioneer being "Hive blog". I expect more DApps to emerge in the future, and it's a good thing. The diversification it'll bring would ensure that everyone has something to offer on Hive, especially in their specific niché.
Few days ago, I stumbled on a post about a new DApp sampling Fiverr's model. I was excited about the news as I feel it'll create an avenue for a lost of interesting things. There was a similar model on Steem called Steemgigs by 
Speaking about DApps, I was thinking it'll be great if we get a similar model to that of Utopian then on Steem. If you joined Steemit early enough, you definitely should have come across the project, or even used it.
Utopian was an amazing project, and the model was great. It faced a lot of abuse though, however, it was a project worthy of accolades until it was sold.
It'll be great to see such project again on Hive. And I think it'll be such a huge boost to the blockchain. I'm certain a lot of oldies on Hive[especially the core founders] know about Utopian, so explaining the model isn't needed.
Utopian helped to onboard valuable individuals on Steem. Most of which are now on Hive. Especially the moderators. I've seen 
Aside from project owners joining steem, there were several contributors making valuable contributions to open source software. And isn't original effort something of value on Hive? I guess yes.
I'm happy for where Hive blockchain resides at the moment.However, it'll be great to start seeing some diversity in the blockchain which can be brought about by several DApps. And I hope a project sampling Utopian's model is developed.
