PubSub

"PubSub is a matching service that instantly notifies you when new content is created that matches your subscription. Using a proprietary Matching Engine, PubSub is able to read millions of data sources on your behalf and notify you instantly whenever a match is made.

The heart of the PubSub service is a powerful, proprietary Matching Engine that makes it possible, for the first time, to match millions of search queries against thousands of new pieces of information every second.

Traditional search stores data and then allows you to find documents within that store of data. PubSub operates by first storing your subscription query, and then watching for new information that matches it. Your query will be checked against every piece of new information passing through our Matching Engine.

Today, PubSub reads over 3 million weblogs, more than 50,000 internet newsgroups and all SEC (EDGAR) filings. In the coming months, we'll be adding many more streams of data, so stay tuned! ..."

More RSS/Atom Fun!

This is pretty cool sounding. I like the "non-standard" items it searchs... SEC, and even Airport Delays! (I don't need to know about Airport delays, but I still think it's cool... and MORE ammo for Feed coolness).

Giving it a try now...
