Blogging in MMO?

Hmm.. interesting idea.
I was reading a news article in BB News. (link)
It says that blog reading is getting more and more popular in America. I suppose the rest of the world too. RSS feed has also become popular for people.

Personally I subscribe to tons of news from all over the world through RSS feed too.

Imagine an MMO whereby it internally provides RSS feed. Like Dungeon clearance in the whole world? Guild News?

Will RSS feed be the future for some MMO features?
hmm....
