Glad to hear that the tag categorisation suggestions were taken on board and getting some attention. Sounds like one of the first logical steps to start shaping the proofofbrain.io front-end into something more unique.
I don't have any suggestions for what the tags should be other than what would be considered the textbook categories such as art, writing, travel, technology etc. It's safe to say that whatever is added will be used for visibility but I'm not of any strong opinion for what they should be.
Great strides forward so far with the community, I'm looking forward to seeing how things progress. Very grateful for the delegation, thanks. Keep up the good work!
