If it's not RSS, it doesn't exist?

I guess in Dave Winer's universe, only RSS syndication sources exist:

New feature: If you do a search on the Baltimore Sun website, you'll see a beautiful white-on-orange XML icon providing the search results in RSS. Subscribe to the feed to peform the search every time your aggregator updates. Don't you wish Google did this?

I guess that the Google feed building support in BottomFeeder just doesn't exist then. Huh. That's too bad, since I subscribe to feeds that way.....
