I saw another person on my flist raise a concern about this yesterday, and I'm a little confused as to why it's coming up now. Bloglines has been around for quite awhile... I've been registered with the site for over a year. Not to mention, every Live Journal account has had an avaiable RSS feed since LJ's inception. (Or, at least in the 2 1/2 years I've had an account.)

Bloglines is only one of dozens, if not hundreds of RSS readers who do the same thing. Yahoo, AOL, MSN, Kinja, and all the Blogger/Blogspot/TypePad blog services are just a couple.
