Brandwatch offers social media listening and analytics. It just announced Unlimited Historical Data, which lets users query three years of historical data from “hundreds of millions” of sources and get answers in a few minutes. The main source is Twitter, supplemented by Brandwatch’s own historical archive. The point here is you don’t have to know in advance what you want to research; everything is saved and queries are returned in minutes. It’s not clear what’s really new here: there are other archives with high speed access. But it’s still a good reminder of what’s possible. Age of wonders and all that.
