Quite a lot of surprises in there - that people are still using Hive Blog for a start rather than Peakd!
And I've never heard of that investawhatevermathingybobthing either.
It's probably the whole PAL crew using Discord to do the commenting, I'm sure if you drop in on @crimonsclad's show tonight you could find out how it's done, someone with the knowledge is bound to be kicking around!
I use hive.blog at times and quite like the simplicity.
Bit busy tonight, got a few zoom beer meetings to attend :D
I also got to wondering whether those Steem posts might also be actifit - you post to Steem through the app, then it posts to Hive, I think.... maybe that's doubling up in your analysis?
There should be a post on Steem and a post on Hive, I think. @mcfarhat should be able to clarify.
