Hey Piotr,

The HF20 may have good intentions and technicalities but what was silly was the implementation. How could you plan an implementation with the entire platform going Kaput for a week? It was just divine intervention that the price of Steem did not fall.

I was wondering and raised this point in different forums, both on and off Steemit, is whether a sandboxing was done before the actual implementation. I am not quite certain because just a few weeks before the HF20, the platform was off for a while. That again was for the HF20 implementation. So, no learning from past mistakes, I guess.

That said, the only visible change, like you pointed out, is the "Hide Resteem" function. This would be helpful when you have to quickly check your own old article and save yourself the time of going through resteems and your articles. The other advantage, of course, is for people who want to participate in some competition and one of the requirement is to resteem the post. So, while they do the resteem, they can hide it from their main page. Works in such conditions.
