“noReplies will show you the recent tweets for a user without any @replies in the timeline.”
Created by @ParterBurn, simply enter a user name and noReplies will bring their latest tweets, displayed over the user’s profile background with only tweets they’ve sent without any replies. Of course, some reply may show up if the @username syntax is not located at the beginning of the tweet. The service also implements a RSS feed in the top left corner, for you to subscribe to. Give it a try!
