Hey, @abh12345.
We probably need to shy away from inactivity as a all or nothing kind of thing and maybe address it from a number of levels. I would imagine anyone with stake here who cares about it and what it's doing will think they have some level of activity, rather than disinterest or a lack of passion or whatever inactivity might actually measure.
At the same time, those that are on most days, for most of the day, posting, commenting and/or curating will be doing so differently. Perhaps different terms for different levels of activity is in order? That probably complicates things, but maybe it gets us where we want to go?
I would think that there would be a difference in the way activity is viewed between the person commenting 20-plus times a day, curating at least that much, plus three posts a week, versus the account that delegates its SP to various other accounts and does little else, popping in from time to time to check in how things are doing based on whatever standards they have for delegatees.
I don't know. Those are thoughts that come to mind, late on a Saturday night as I try to wrap up another week of engagement. :)
