I keep wondering if we can discuss data. We're all driving data API's and some of us must save the data as we gather it. I'm gathering the social graph (which accounts read which accounts). I'm sure many people gather many datatypes and metrics. It makes some everybody-wins sense to me to trade or share data.
for example, today i can offer 17million who-i-read datasets collected over the last 4 months. and i want: a list of active accounts, by id, by some sensible metric. (a list of inactive accounts would equally help.) a list of tweets-per-year metrics, perhaps derived by extrapolating from the oldest of the 20-status api calls. i'm sure there's a variety of usage information i could apply, so i'm curious what you've collected. In summary, my topic isn't the API, it's a valuable byproduct of using the API. I realize there are so many scenarios, and not everyone is warehousing data. I'm also particularly keen on keeping valuable data away from spammers. But those who collect data for valuable software ought to build a clearinghouse, and build data-sharing relationships so we all hit Twitter less and serve the community better. What do you think?
