Ah right, well, Memo is a much simpler form of social media platform, for chats, adding links etc, like Twitter but more rudimentary (early stages of this type of platforms) with one massive difference, which is that everything that is being posted here, is permanently stored on the blockchain, can't be changed/edited or deleted, which also means it can't be censored. There is 2 separate versions of Memo, one is based on BSV blockchain and other is on BCH blockchain... they are Memo.sv and Memo.cash respectively. There is difference between the 2 in that on Memo.cash you are limited to much smaller number of characters per post, I think its something like 250 characters or around that number, while in Memo.sv you can post up to 65,000 characters (you can see characters count in top of the post as you type it). There are topics, you can follow topics, users, (un-follow also), make your own topic, etc. You can tip people, note that tips are counted in satoshis... but maybe you...
