Twitter Sockpuppet

This pipe retweets the tweets in a twitter search: your+search+terms. It only retweets original posts, not retweets, and removes your own tweets if you enter your Twitter username.

Discussions

This pipe searches for relevant discussions by keyword. Currently only reddit, but more to come!

Video News

This pipe receives feeds from various video sources, filters non-unique items and sorts results by publishing date.

Via friendfeed

This pipe uses your friendfeed source as an alternative to gathering data from within the yahoo pipe. You gather data on friendfeed, in a group or as an individual, and feed it to this pipe. Future developments are recognising source and rebuilding output strings based on that to link directly to the sources, and removal of the frienfeed source image associated with the friendfeed user or group name.

Art and Images

This pipe receives a deviantART and Flickr feed and returns a new feed with images.

Breaking Google News

This pipe searches through Google News sources. 

World Tweets

Searches for a keyword on Twitter and creates a map with tweets.

I have big plans for this pipe. Like including blog articles, video, music and art that appears for keywords during operations.

Thumbs

Internet Headlines

This Yahoo Pipe aggregates search results from various sources, filters the results, ensures the links are unique and sorts the results by date in descending order.
