I've been working on a simple search concept which basically uses the search api to set a live list of responses to a given search string http://search.twitter.com/search.atom?q="&srchterms
but to determine if any response is the basis of a conversation, th only way I know to do this given the api is to make another call to get the status for a given response, using http://twitter.com/statuses/show/STATUSID.xml and check out the "in_reply_to_status_id" node this results in a quick over capacity reply from twitter (i had put in a whitelisting request, which was granted buy still getting kicked out after 100 requests per hour) is there any other way to get this information (i.e., find out the the conversation that a given post is part of? Thanks, Allen
