Blog reader app with tagging

[Davor]

I have been using my iPad for about a month. I track a lot of blogs using google reader, and have been using the MobileRSS app to read the blogs. I like the interface but am frustrated with the inability to uses tags. When I use the google reader online, I tag nearly every blog so that I can go back and find them easily. Is there a reader app that offers this feature? Please help.

Thanks
