I’ve made quite a few Yahoo Pipes lately that do some interesting parsing, filtering, and hacking on RSS feeds:

Yahoo Pipes Twitter Reply Sniffer

Find Twitter replies whether you follow the person replying or not. The Twitter Reply Sniffer pipe outputs an rss feed that finds all references in Twitter to @yourusername. Thanks to Justin Kistner for the making the first version of this pipe that I have been updating and tweaking. Get more details about how the Yahoo Pipes Twitter Reply Sniffer works.

Usage:

  1. Go to the Twitter Reply Sniffer
  2. Enter your Twitter username and click “run pipe”
  3. Grab the RSS feed output

FriendFeed Minus Twitter

Use this FriendFeed Minus Twitter Yahoo Pipe to get a nice little RSS feed of your FriendFeed without the million Tweets. Get more details about how the FriendFeed Minus Twitter pipe works.

Usage:

  2. Enter the RSS feed from your “friends” page and click “run pipe”

FriendFeed Comment Finder

Don’t miss any more FriendFeed comments. The FriendFeed Comment Finder attempts to find content with comments or that people have marked as “liked”. Get more details about how the FriendFeed Comment Finder works.

Twitter Filter for Events

I originally wrote this pipe to find any Tweets with sxsw or Austing anywhere in the text; however, you could clone this pipe and very easily change it to monitor any event (or set it to filter out event tweets). Get more details about how the Twitter Filter for Events works.

Usage:

  1. Go to the Twitter Filter for sxsw
  2. Enter your “with friends” Twitter feed URL and click “run pipe”
  3. Grab the RSS feed output and put the feed in your favorite mobile RSS reader.

Find Top Blog Posts Using Yahoo Pipes with AideRSS

Avoid missing important news or ideas that everyone else is talking about. The Top Blog Posts pipe takes some of my favorite blogs as inputs and sends the posts through AideRSS to find the ones with the most comments, discussion, bookmarks, etc. Get more details about how the Top Blog Posts Using Yahoo Pipes with AideRSS pipe works.

Usage: This pipe is not yet customizable, but you can get the RSS feed.

If you are new to Yahoo Pipes, my Power (and Pain) of Yahoo Pipes for RSS Aggregation is a good place to start learning. I’ve also included some recommended reading at the bottom of the post with links to a few other introductions to Yahoo Pipes.

You can also view the source or clone any of my pipes if you want to find out exactly how I created them. In general, they are pretty easy to tweak, so I would encourage people to clone them and tweak the source to meet your needs.
