Over at http://birdhive.net, we track our friend timeline to find people who have marked tweets with the #bh hashtag. Until very recently, I thought that passing the optional since parameter in my request would return all tweets in that timespan. It was only recently that I realised it just returned the default 20 tweets, filtered to fit into that timespan. A big goof on my part.
As a result, we've been missing some tweets. In response, I've set the count parameter to it's maximum of 200 and have increased the frequency of my cron script. But this still seems shaky. I feel I should be using the search API, but can't find a way to filter results to only show a friends tweets. Any suggestions?
