I was stunned to learn, via Danny, that our collective tweets seem lost to eternity (or at least, to search). While the data exists, tweets can’t be found via search, which means they can’t be found via the search API, which means…well, they can’t be found. I hope this situation is rectified, if only for history’s sake.
(Danny notes that they can be found using Google or Bing, at least for now. That’s a relief. But it does not bode well for Twitter’s ability to scale.)
