@amacilin's answer pretty much nailed it. But I wanted to counter a few such assertions /r/Bitcoin often makes about decentralised being better than centralised.
Recently someone said something to the effect of "Blockchain based storage/websites is the answer to the centralised server solutions, which have been around forever"
The thing is, centralised services have been around forever because:
- They work
- They work very well
- They're cheaper to maintain
I know this isn't the question you asked specifically, but I thought it prudent to answer since often the excitement of "can it be done?" trumps "should it be done?.
It's also pretty prudent to question how moderation would be done. Even if if you're a staunch anti-censorship/moderation supporter, I don't know how one would ever sort through the crap without needing some moderation.
Essentially what I'm saying is the "issues" with centralised servers are probably not worse than the problems with using a decentralised service. And this isn't even considering the privacy implications!
