Are you sure about this, Bruce? During the last four weeks we were
using the Twitter api and as a matter of fact we've managed to write
our own Python script (optimized over the existing ones) to harvest
tweets backwards in time and the best we could get was just a week in
advance. Notice that we were using search terms which were valid
(active) in the past as we could see the flow of these tweets inside
the Twitter site search (but we could never retrieve more than a week
back in time through the Twitter api).
I agree with Alex.
