To be fair he said "lack of desire for lots of social interaction" -- with emphasis on the word "lots" -- and not "lack of desire for social interaction".
cortesoft may very well be needing social interaction (inasmuch as Maslow's hierarchy of needs is fulfilled), just not lots.
I'm not sure it's entirely frivolous...

On the one hand, I can think fairly deeply. Yes, I do regard that as a positive quality. And yes, a lot of social interaction gets in the way of that. ("Interruptions shatter mental momentum" - I forget who said it, but when you're trying to think deeply, it's really true.)
On the other hand, I need human interaction - maybe not as much as most other people, definitely not all the time, but I need it. I need to be able to be a person, not just a thinking machine.
So maybe I'm "unsocial" without being "anti-social"...
