The deeper the relationship, the greater the proportion of it dedicated to triviality; and beyond, say, 90% triviality, the relationship isn’t a relationship at all. And likewise with meaningful interactions—if everything is meaningful, it’s not a relationship, it’s therapy.
Web Social Architecture: Twitter: Trivial. Beautifully So.

@Ario posted the heart of this quote to Twitter, of course. However, it’s the smartest things I’ve heard this year. Easily.

More smart stuff, directly about Twitter:

So I’m arguing for Twitter, or an analogous triviality service (ha!) as a supplement to existing relationships, not as a full-fledged social channel in and of itself. As a social network, I actually do think it’s useless, or worse. And you can take that as a caveat.

But I am saying I think triviality in general and as supported by Twitter, in both personal and professional settings, is indispensable—that we can and should deliberately design it into social systems.
