I really like being in control of what I see of a site. I'm ok with checking when I want something, and I prefer to be left alone when I don't want the info... this sounds somewhat promising, for certain things, but I don't really think its for me. Maybe its the old man in me but I am somewhat protective about my email inbox.
In reply to andrave:
No email inbox activity from RSS necessarily. If you've got a mail client you also configure as your RSS aggregator, it'd be in the same place, but you don't actually receive any email.
I use google reader, so there's a web page I go to that shows if there's any new stuff waiting for me from any of the feeds I subscribe to.
