Cameron, Chad, and the Tweetfall duo pinged me this afternoon to let me know there is a new error cropping up from the search API. The error text is "since_id too recent, poll less frequently".
I found out that is a permanent addition to our error checks from the maintainers of the search code (the software that powers the API). If you are seeing this error and you believe it is a mistake, please reply with the details. Simply put, we are running thin on search capacity so the team is pulling out the stops to keep clients honest. Thanks, Doug Williams Twitter API Support http://twitter.com/dougw
