You've nailed it with your comment!
It's about supporting the new community members.
I've recently started making an effort to connect with new members and re'steem some of their posts. Getting a post re'steem'd is truly an awesome experience. I know I appreciate it immensely. It's real honor and the gratitude is a great big wow of thanks.
Like you say: spreading the wealth around - Yes Indeed.
Expanding the Community really is Everything
100% YES, This is It. And it's about the principles and Integrity you so eloquently listed above...as expansion only really stands the testaments of time when it's well built :)
Have a great 4th of July Brother,
All the Best, Always :)
