I came across another data sharing site today - www.trendrr.com.
It's very reminiscent of Swivel - same type of layout but with a definite concentration on trend data from social networking sites, Google, blogs etc.
The description of the service on the site is:
"Track, compare and share data, free. Identify trends across social graphs and networks, realize the potential of p2p, track engagement metrics, look at what is really happening, real time."I was more confused after reading the description to be honest. But from the look of the site, it has some type of voting system for trends - sort of a Digg meets data.
I might have a play around with it if I get some time. Although at some point it has to occur to people that data is not like news - it doesn't lend itself well to syndication, commentary or reproduction in any way that takes it out of context.
