Re: Can We have bitcointalk user interface changed to something like Facebook UI?
What is facebook? 
I don't use it because it is full of UI ( useless information ).
Why bitcointalk.org, which has strong position in crypto, has to follow Facebook, that is a newbie in crypto? My opinion is: NO. Not only because its UI (Useless Information, mentioned by @JetCash), but also its nearly useless Facebookcoin, namely Libra. There are a Libra's WhitePaper, and theymos' first opinion on Libra after seeing its site and whitepaper.I don't use it because it is full of UI ( useless information ).
If they make a permissionless cryptocurrency similar to Bitcoin, good! Then freedom in the world will be increased. But I really doubt that this is going to happen. Right now their paper reads like a standard scamcoin vaporware paper, and I currently judge there to be approximately 0% chance of them actually allowing anyone to use the system anonymously and freely like you can with real cryptocurrencies.
