Another possibility is to make another site/client to compete. That usually spurs innovation. We'd still all be talking to each other on the same blockchain & memo protocol.
Also, if you can put TXs in the blockchain that conform to the memo protocol, they will show up in this app as well, even if you use your own software to do so.
Each like is .005 BCH which is $3.05 right now? Looks like I have "599,436 satoshis (0.00599436 BCH)"... So one more "like" and I won't be able to like posts? Or post?
If you can retrieve the transactions (TXs) from the blockchain that have memo protocol data in them, you can display them. You can write your own code to do so if you are tech enough.
It's pretty technical even for me being a programmer/software developer of over 20 years experience, so I haven't even attempted to set up my own instance of it to begin working on it.
If you can manage that, then I think you will know what to do next. It is a long journey though. In lieu of that, helping adoption and telling friends about memo is great too.
If you have programming ability though, my suggestion would be to try to understand the fundamentals of bitcoin first, then use a library to create a memo post.
You mean the technical fundamentals of bitcoin? Bitcoin is digital cash, making money permissionless and immutability via blockchain technology? This reply to you is a memo post?
