isn't that a bit like clipping coupons from last year's newspaper?
Heh. I think there's more out there in the historical Twitterverse than just coupon codes.
Just in the last 12 months, consider all the grass-roots reports, observations & campaigning and peer-to-peer discussions on national elections, on the protests in Iran, on the disasters in Haiti, Chile and now China...
This is going to be a tremendously useful tool for researchers, historians, academics and journalists.
Well done, Google.
