I don't think it will turn into a ghost town. HF20 was a necessary path. People forget its only two years old. Other front ends like @steempeak provide the information your looking for about manna.
The fact the so many people have complained so bitterly about being down for a couple of days shows you how many people have are actually attached to this whole idea.
Thank you for being so responsive @intrepidphotos
Steemit indeed needs more people like you.
Appreciate, Piotr
Steemit will get there; we just need to give it time.
