Best of all, it’s not a silo like Twitter; it’s built with the tools of the open web. As Brent Simmons puts it:
We could be excused for thinking that Micro.blog is like App.net — a Twitter alternative greeted with enthusiasm but that eventually closed.
It’s not the same thing, though, and I’ll explain why.
Micro.blog is not an alternative silo: instead, it’s what you build when you believe that the web itself is the great social network.
That’s the important part: even if Micro.blog doesn’t last (though I believe it will), the idea — that the web itself is where we are and where we talk to each other — will continue.
