I personally don't get the obsession with changing everything to decentralisation, since it isn't something that needs to be implemented into everything, in fact I tend to believe in certain situations, decentralisation is a horrible idea.
So far the forums have been great and there's no need for changes that can look like wild social media.
This is indeed a Bitcoin forum and as we all know that Bitcoin is a decentralized currency, it is not necessary for this forum to be decentralized. It means I agree with you that not everything should be changed to decentralization.
The last change proposed by our friend @PowerGlove has been approved looks pretty good, namely the placement of (OP) in each username to indicate the person who created the topic.
