I'm just reviewing the API docs, and I'm not clear on something. http://apiwiki.twitter.com/REST+API+Documentation#replies
If you pass in a since_id, then do you get ALL the results since that ID, or just the latest 20? I'm planning to ping Twitter every minute and collect the @replies sent to a particular user. I'm sure I won't get more than 20 @replies per minute, but I would like to know if that's something I should note for the future. Thanks, - Trevor
