What's the benefit of twetch over twitter - is it free spee…

One's a scam and the other is run by Jack Dorsey

No, Twetch can censor you if you're doing illegal things. If they do however, you won't lose your data, as it is stored on the blockchain, every interaction here is. So you can copy it to other apps or just keep it for your own reference. The real value...

Is that you can earn money from every interaction, and from every interaction your interactions spawn. If you can seed meaningful interactions that create activity, you get money for each one. If you game it out properly, you can make some dollars.

There are also many interesting features. I can set up a troll toll that charges certain users more for interacting with me, so trolls have to pay me for the privilege, again if you game it right you can make dollars. Explore, it's early, but interesting.

It's not a scam, it's a very serious technical achievement that can provide a venue for novel human interactions, that haven't been seen over the internet before.
