Who needs Twitter follower notifications clogging up their inbox? Why doesn't Twitter provide an RSS feed? And why isn't it easier to identify spam-followers?

Turn off those pesky emails and get your updates in RSS with Twitter Follower Notifications.

This tool uses Yahoo! Pipes to create an RSS feed that gives a ton more info about your new followers, like:  

-Their bio and location
-Their last five tweets
-Whether or not they follow you, too
-Whether their updates are private or public

Bonus: you could use this tool for any Twitter user, which could be useful for seeing whos following friends or other 'persons of interest'.

Walk through the code and see how amazing Yahoo Pipes is - instant mashups without the need for tools or a server, all in a beautiful UI that makes it easy to share, clone and build on other ideas.   And YQL makes the web a huge database for your app. 

Twitter Follower Notifications was built by Marsh Gardiner (@earth2marsh), who uses Apigee to give him traffic stats and alerts to help him better understand how people use this tool. He's also been very active in the Apigee feedback forum, pushing us to make Apigee even better. Thanks Marsh, we're listening!

Need to compare prices for a blueray DVD ?  Or baby car seats?

Shopdiggity.com offers a streamlined comparison online shopping experience across hundreds of product categories and brands.

Shopdiggity has a fast, clean UI that makes browsing Shopzilla's massive product catalog more approachable.   It's a great example of an app that adds value and monetizes a publisher API and affiliate marketing program.

Christopher, Shopdiggity's owner, uses Apigee to monitor performance and response times from Shopzilla's API.

Some great feedback from Christopher -  we need to add more email alerts so that developers can respond to changes in API behavior.  For example, if the Shopzilla API has slow response time, an alert would help him adjust ad campaigns to balance between user experience and monetization.

Thanks to Christopher for the great example and the feedback on Apigee.   If anyone has more,  please hit us on Apigee's Get Satisfaction forum.
