I'm defining "social network" pretty broadly, including websites that have a strong social component, like HN, reddit and imgur. These kinds of online communities tend to make people happy, and they let them form friendships and exchange ideas. If a new one emerges then it's probably making some critical mass of people happy. I would guess that Yahoo's audience might not have a ton of exposure to all the different social networks out there on these days, and they might appreciate a stronger community aspect to Yahoo. A Facebook clone wouldn't make sense, but something that gave it more of the flavor of imgur or HN might. Though I suspect that would be really hard to pull off. It wouldn't be the bet thing for Yahoo to focus on, but it wouldn't be the worst.
