yes i was using twist as i saw it on TechCrunch. I got to 200 out of 1220 tweets regarding my topic, where it said something like unable to show more then 200.
I assumed this is due to Twitter's API? If that is not the case can you code it to show all results on a topic from day one?
Though Im not sure what VCs or angels will think when I present my data being from Twitter. But to me its a cheap and solid way of gleaming demographics on topics; albeit the demographic is skewed for now.
