Thing 4-RSS feeds

I set up my bloglines but didn't get the confirmation email. I saw on the comments that this appeared to happen to others too so I set up a different RSS feed with google reader. I already use several other google tools such as bookmarks, notebooks and docs to share documents with others online. Can we use a different one than bloglines? I'm not even sure I am using the right words for the collecting of blogs and news. :)
I have already found several blogs and subscribed to them-I can see that this is going to be very addictive (and my husband says I spend too much time on the computer).
