The greatest proof of attention that I can take seriously is when my readers and followers engage in conversations and dialogue with me that could only be a result of having read what I write. This of course leads me to having "favorites" who I interact with frequently, who (at least appear to) give a damn about what I have to say.
We all have the same (limited) amount of time every day. There's only so much we can read and genuinely interact with.
While it might (initially, and for a while) be interesting to interact with an "AI / bot" reader or follower, I think in the long run I still will crave real people who actually read what I write and benefit from it. ;) 😄😇😄
I suppose PoA is the sum of all interacts, etc. Now if there's a good way to measure such a thing! When more people come into Steemit, I think it's time to think less about what to post and more about going through stuff and leaving comments / replies. And also, talk less about Steemit haha!
