Nexus



Another cool data visualization tool. This one graphs out your friend network from Facebook. Here's my friend graph. It's is pretty cool how neat clusters are formed between different sets of your friends, like your old school buddies, undergrad/grad school friends, work friends/colleagues etc. And how some people act as "Connectors" across multiple groups. Studying social graphs has been around for a while now, and it is nice to have simple visualization apps which everyone can use easily.

What are those dots with no edges?
And why are some egdes colored differently from others?

Talking of social graphs, there was this interesting paper in Sigcomm 2 years back called Sybilguard. It used social graphs to prevent sybil attacks (impersonating of multiple identities). Basically the idea is, the impersonator can easily create multiple IDs, but cant easily create social graph edges.

Dots with no edges are those of my friends which are not connected with any other of my friends (The graph doesn't have me. Would be kinda redundant). And I think the thickness of the connecting line increases with the # of things the 2 friends have in common (groups, interests etc.)

Nice application of social graphs. I heard that Gmail was (is??) invite only, so that Google could trace back the referral connections for spammers to the nearest legitimate users. Not sure of the veracity of this though.

Or rather those of your friends who have a real life outside the internet :-p
