The Steem Blockchain is immutable, that's true. But that does not mean platforms arent able to filter the signal from the noise. We'll soon see a much less spammy and much higher quality content on this platform.

Musing is still pretty much an MVP, so us early users really will have to bear the brunt of the bullshit that an early platform will face, abuse, spam, bugs, all that and 101 other things no one can predict.

I have full confidence in Musing though.. It's gonna be one of the Steem killer apps for sure.
