Publishing it, yes. Mostly on my blogs these days, though I used to use RSS to help sales people manage content across a number of websites owned by a wine distributor.

Interacting with it, sure--at a paid service level it's been easy to monitor service updates this way, but not so much at a personal reading level currently. Though you got me thinking...

Last time I was using a reader, I remember struggling to find a Linux desktop RSS reader with discovery features. I have my own OPML that I like & cart around, but it requires a lot of maintenance over time, and using feeds for their current value seems to subvert the fact that a lot of really great blogs are past their heyday (the good stuff is found by going back in time, not so much now & later).

I also thought it'd be cool if there could be a P2P effect with sharing OPML or RSS feeds, like a general catalog. Or let's say a Gutenberg.org mixed with Github for RSS. Find, explore, & remix others' shared feeds. Not sure if such a thing exists.

Almost some random thoughts here, not sure if any of this helps...
