My take: It doesn't matter that most currently private subs will go back to being public, and that posting on those subs will return mostly to normal.
What does matter is that several thousand of us were inspired to look at something different and are intrigued enough to keep plugging along, helping to further the case of decentralization and demonstrate, in a small way, what a better future can look like.
I'm likely going to return to Reddit, but I'll do it with an eye on making something better for the subs I'm active in.
