Another brief, interesting idea sparked off the Nokia Open Lab event at the weekend. I mentioned to Jenifer Hanen (@msjen) that I followed her on Twitter because we appeared to have an exceptional number of mutual friends.

Following someone who repeatedly appears in my feed seems natural, and I’ve met several people that way: by discerning a social network made up of conversations between friends and second-degree contacts who show up in my Twitter feed. All of this supports the idea that Twitter is a really good, transparent, conversational tool.
