re: relate and interact
I think you're right. Having access to everyone from tags or however people manage to do it is actually good, rather than needing from blog to page like you might on FB. I mean you can search and scroll through on FB too, I guess, but with the tags, it just seems easier, and then after that, you know who's active and who's posting compelling stuff.
re: eagle tokens
Not sure about the eagle tokens or how they work. These are engage tokens, that Asher created on Steem-Engine a while back and I guess he's got them capable now of being dispensed with comments. That just recently happened. You need to hold 1,000 ENGAGE tokens before it will work, and then you can dispense up to 100 at a time. There's a limit on how many can be given out each day, I believe, so if that limit is hit, there's supposed to be a message that says something to that effect.
