Twitter + Yahoo Pipes

Via Conversations: How to create a Yahoo Pipe of your friends’ tweets that contain URLs: 

Here are the steps once you create your Yahoo or Pipes account:

1. Go to your Twitter home page and grab the RSS feed.  If you have trouble finding it, it’s at the bottom lower left of the page and looks something like this: http://twitter.com/statuses/friends_timeline/915051.rss
2. Go to this Yahoo Pipes page and "clone" the pipe. You’ll find the "clone" button center-screen, just above RSS feed icon.
3. Click on "edit source", which gives you a screen like this:
   
4. Replace the Twitter feed in the clone with your own (see step 1). Save (upper right of the Pipes screen) and publish.
5. Grab the RSS feed and subscribe in whatever aggregator you use.

Press Releases Via Twitter

Forget the twitpitch, you can get actual press releases via Twitter! The press releases come from Journalism.co.uk by following pressreleases on Twitter. However, that might be too much of a firehose, so they’ve also let you narrow it down by category. On this page, you can subscribe to either the RSS or the Twitter user for press releases from various categories that include everything from agriculture to government to construction to engineering and more.

EasyTweets

EasyTweets is a web-based tool that lets you manage and post to multiple Twitter accounts. The service offers several features including automatic URL-shortening, the ability to type more than 140 characters, the ability to have your blog linked to Twitter to auto-post blog entries, and a scheduling feature. You can also use EasyTweets to track replies and see a list of your followers.

Feedtweeter

Feedtweeter is a service that lets you link Twitter, Plurk, and identi.ca to other activities. It lets you multi-post to those services – post a plurk and it will show up in Twitter, too, etc. The service is still in beta, but they say it “should” let you send any RSS items to Twitter, too. Future additions include flickr, YouTube, del.icio.us, send to blog, and send to email. To get an invite code send a tweet to @steffest.

Twitlinks

Get a river of tech news via Twitter with Twitlinks. This server monitors the tweets of a bunch of tech bloggers then displays them in an easy-to-read format. Each item gets a link to the story, the story’s first paragraph, and a link to the Twitterer. You can even subscribe to the output by using the site’s RSS feed.

Techmeme Firehose Twitter Feed

Some news junkies thought that the "normal" Techmeme Twitter account was too slow. Also, the main feed only focuses on the day’s most important 20-30 headlines. A new "firehouse" feed and Twitter account have been created for those who want it all. The Techmeme Firehose Twitter user will give you that real-time news experience, but it’s not for the timid!

Twitter Link Monitor

Scott from TechLifeBlogged created a Twitter/Yahoo Pipes tool called Twitter Link Monitor. Since Twitter offers up feeds via RSS and Yahoo! offers their Pipes tool, he was able to build, filter, and subscribe to a feed that gives him only ‘tweets’ with links in them. If you have a Twitter account you can use it too. Go to http://pipes.yahoo.com/techlifeweb/twitterlinkmonitor and enter your Twitter user name in the field provided then click Run Pipe.

TwitterWhere

The service called TwitterWhere lets you generate an RSS or XML Feed to filter out tweets around a certain area. To use TwitterWhere, you just enter a city, state, postal code, choose the range of miles you want to include, and hit the button. You’ll instantly get URLs of local tweets that you can add to your RSS reader. The TwitterWhere site also offers an Adobe Air app that lets you track tweets from your desktop, as well as show friends timelines, replies, and send updates

Twitterfeed

If you’re a blogger that uses Twitter, you’ll want to check out twitterfeed, a service that feeds your blog to Twitter. Using twitterfeed, you can get your blog (or any other RSS or Atom feed) twittering. You login to twitterfeed using your OpenID and provide the service with your blog’s RSS feed and tell it how often to post to Twitter. The twitterfeed server will then check your blog’s feed at the specified interval and post any new items to Twitter, which no further action on your part.
