Ah, I didn't know that! LJ never seemed to make a statement about just why they only supported personal RSS feeds, not an aggregated one of the Friends' Page. What made no sense to me was that someone could achieve the same effect if they just subscribed to EVERY SINGLE FRIEND and community's RSS, but for folks with hundreds of friends and/or communities, that's not only tedious, it's difficult to stay organized.

I'm hoping it can be implemented keeping individual user's syndication choices in mind.
