Interesting conversation going on at Jason Kottke’s site on RSS 1.0 and 2.0. As a feed provider, my primary concern is shipping out content to the most consumers, and if I need to use two formats to do that, that’s fine. My use of RSS 1.0 will be pretty limited to cutting and pasting similar fields from 2.0, I guess, until I find some better documentation on how to manipulate it.
I’ve found a few of the aggregator sites prefer or require one format over the other, so providing both is pretty much required. Looking forward to finding out if more advanced tool can be built with the more complex format.
