All friends aren't created equal (why we need better relationship marking in social networks)

I'm the guy who wrote this blog entry on relationship marking and grouping, and I just found this news.ycombinator.com site via my referrals.

Of course, I was familiar with ycombinator, but not this news page. Thanks for including my article here, and timg, thanks for the kind comments :)

Specific and interesting suggestions. Nice ideas.
