If I understand things correctly that is what "hivemind" is supposed to be. A layer that handles tags, follows, and other things that don't need to be immutably added to the chain. That might also be why the marked it as "wont fix" because they aren't going to fix it within the chain but as a part of a second project.
The last part is conjecture, but if you've dealt with many programs you know some lack social graces and this sounds like one of those issues.
That is likely, yes. It would be good if they would have explained that in the Github ticket though.. And we are still left guessing and unclear what to do with our own development in relations to such an important issue.
It sounds very plausible, from a programmer's perspective.
And yes, sorting and searching would very much need to be a layer on top of the blockchain.
OR, you just search through the entire chain for everything. (truncated of course... you hope)
So, basically building a sorted database as people access information. Is what i picture when i read "hivemind".
... i hope they are not intending to build a permanent database... the resources would get huge.
(and the only way this is not conjecture is to be sitting in Stinc and completely knowing the back end)
@Steemsql and other databases already exist as a database form of the blockchain and I use it for Steemocean.com - but yes, the resource load is high, so I hear.
