Cool service but it's beta until now, you can config your account to send instant messages and I think this is one of its advantages...

Subscribe to a blog or web site with an RSS-feed and get notified when it is updated. You decide when and where to get notified – Queoo sends you e-mails or instant messages on a schedule of your choice. It's free!

-Queoo monitors your favourite feeds and compiles lists with blog and web site updates.
-Queoo notifies you when you want it to, in between you can stay focused on other tasks, relieving you from constantly looking for updates.
-Queoo notifies you with e-mails or instant messages so there is no need to install any RSS-software.
