Adam Kalsey, a founder and former CTO of RSS vendor Pheedo, has released a new service called FeedCrier. This service makes it easy to receive IM-notifications of new items in an RSS feed, just like the Rasasa-service where I wrote about before.
FeedCrier currently supports only AIM but that will change soon. Free accounts are limited, premium subscribers ($4 per month) can monitor an unlimited number of feeds, remove ads in the alerts, use a web interface to manage their alerts (via techcrunch).
Competitors include immedi.at and Zaptxt.

Rasasa is a Dutch RSS reader with a twist. It will send new RSS items to your messenger, if your online or text message you, if your offline (via kbcafe.com).
