I know there are quite a few of these services but this latest from ZapTXT caught my eye when I found it mentioned on Mashable.
This new version lets your RSS feeds find you. If your logged into IM it will send you them as an IM. If your idle, away, or logged off you can get them by email. You can also have them abridged or only sent when there is a specific keyword. You can also set quiet times so it does not email or bother you at night.
Kind of a cool service for those people who just have to always have the latest news at the tip of their hands. Check it out at www.zaptxt.com. I am trying it now. If I like it I will report back.
