You needed a fork to check those out? handcash and keyport didn't stick with me, but I was a huge fan of moneybutton. I was even seeking out sites that used it just to be able to use the slick slidy thing... so much fun.
I left moneybutton and yours.org when Ryan X. Charles went ballistic and started banning people and deleting their content on yours.org. After the misguided policy of accepting only transaction valid on both chains (I lost money due to that) it was just too much. This was a huge reason for me to "be against" BSV.
Now there's
https://honest.cash and moneybutton replacements like badger button.
I just got a handcash-compatible smartphone two weeks ago, maybe this was another reason ... With MoneyButton, I was first very disappointed to see Ryan focusing on it instead of yours, which was a thing I liked very much, and I needed some time to understand what it adds to just posting an address. After finally testing it and reading the html docu, I became absolutely fascinated.
If you followed r/btc in the weeks before the fork, and all the shit that was thrown on Ryan for just being undecided and trying hard to keep the things together (you call it misguided, but it was a desperate attempt of doing the right thing), I can understand him overreacting. Also he did something very very rare in our space: He publicly apologized.
I have not deeply investigated honest and badger button, but I'm not confident you can simply copy Ryan's focus on creating highly usable apps.
Cashport (handcash + keyport): Reserve an amount in your wallet, login to any side by scanning a QR-code, automatically paying a service like movies, music, articles and so on. Imho this could be a revolution for the content industry. Imagine this done with netflix, or with music streaming for artists.
