My First Tweet is supposed to find your first chirped status, but it apparently fails if you have gone past the 3000 mark.
There used to be a way to manually page back through your twitter archive by munging the page=XX value of the old URLs… but they took that away.
So where do old tweets go?
Nowhere, they still exist– but for whatever reasons, twitter.com does not provide access to them.
So I searched my blog for references to URLs where I may have linked tweets, searching on http://twitter.com/cogdog/statuses/ and thus found a reference to likely one of my first, as I started tweeting in late January 2007 — the URL still works but HTF can you find it from twitter’s interface?
Bottom line- your old tweets are there, hung in suspended animation.
Free the tweets! Free the tweets?
