What percentage of all tweets are replies to others, i.e. contain @nick? We do research on dialogue and I'd like to get as many conversations as possible. So far the only reliable way I see to do it is crawl. Even with the /gardenhose I'm not sure that I'm capturing enough from each conversation. Perhaps /follow can be harnessed for it, but then I'd have to determine the people of interest who converse enough. Perhaps you honorable Twitter Spirits can add a "replies" stream?
Cheers, Alexy
