It all started few days back when i actually wanted to categorize my twitts. Say I want my tech twitts and friends twitts and celebrity twitts all separately and can be burned in a feed burner on my browser to get on the fly updates. Option was Pipe and eventually this is what i created. Go ahead and give a try. I have defaulted the text inputs with my id, 2 celebrity id and 1 engadget id and the feed is a merged twitt of every one and sorted by time. Let me know your comments.
