byTagg is an RSS Reader/Alerter for Blogs and Twitter

ByTagg is a new solution that will let you follow your favorite blogs and know when they are updated right on the spot. This is accomplished via alerts that are sent whenever any blog or site you have specified is updated.

You can also subscribe to keywords instead of feeds. You can enter in a keyword (ex: "twitter," "obama") and then check a box as to whether you want to see results just from news sites, just from blogs, or from the entire web.

A Twitter search feature lets you configure keyword alerts for a specific person's Twitter account. You can do the same for your own Twitter account.

And more! With byTagg you can:
+ read RSS clean and easy
+ setup an active search and you get notified on new search results
+ follow and interact with your Twitter friends
