I've implemented RSS feeds for user edits
Posted by Ævar Arnfjörð Bjarmason on 7 June 2009 in English.Which I managed even though I suck at RoR
But check it out on the dev server. I'd be especially interested in any practical applications of the georss tag. Do any RSS readers support this?

Actually not only for the user edits but also for recent changes and history within a bbox now. See the ticket in trac.

I see the changeset was taken back out into a branch for now, but it would be good to see this improvement get in after it's had some tweaks.
In terms of RSS readers that support GeoRSS, I'm not sure, but services such as Google Maps will allow that feed to be overlaid on their maps as a quick reference, and also feed aggregators such as Drupal's FeedAPI will pull out the geodata and allow it to be stored using the Location module.
