So what features of this will eventually be implemented into Steemit.com?
I'm not a developer, but checking the Github links you've provided, I am seeing some very exciting stuff:
Hive tracks posts, relationships, social actions, custom operations, and derived states.
- discussions: by blog, trending, hot, created, etc
- communities: mod roles/actions, members, feeds (in 1.5; spec)
- accounts: normalized profile data, reputation
- feeds: un/follows and un/reblogs
Hive can be extended or leveraged to create:
- reactions, bookmarks
- comment on reblogs
- indexing custom profile data
- reorganize old posts (categorize, filter, hide/show)
- voting/polls (democratic or burn/send to vote)
- modlists: (e.g. spammy, abuse, badtaste)
- crowdsourced metadata
- mentions indexing
- full-text search
- follow lists
- bot tracking
- mini-games
- community bots
