Twitter status ids are fast approaching the maximum 32-bit *unsigned* integer value (4,294,967,295).
The current estimate is that this will occur in approximately 60 days, at the end of September. The 60 day window is a best-guess approximation based on projections. It could conceivably happen sooner. Developers are encouraged to not only update their applications to use a 64-bit integer (BIGINT/long long), but also verify that all libraries they use are also prepared to handle 64-bit integers. -- Marcel Molina Twitter Platform Team http://twitter.com/noradio
