Robert Sayre: Next time someone tells you Atom 0.3 is invalid because the validator says so, point them to this page. The validator is full of it, because it doesn't reflect reality.

Randy: I'd like to add, that from my own feel of the market, more RSS aggregators support Atom 0.3 than Atom 1.0, but I don't have any data to back that up. That said, you can be certain that support for Atom 1.0 is increasing. Whether it will ever rival RSS 2.0 is another story. Is Atom 0.3 invalid? Let's examine the version number. It starts with a zero. RSS 0.91 also starts with a zero. If I were building software and I published a format whose version number started with a zero when a newer version that starts with a positive integer is available, then I'd have some explaining to do. Is Atom 0.3 or RSS 0.91 invalid? NO! Are they deprecated? YES! Should you publish them? NO! Do RSS vendors have the right to say they are not support those version without repercussion? YES. IMHO.
In fact, I think I'm gonna remove support for Atom 0.3 and RSS 0.9x from Rmail. Sorry Blogspot. Get with the plan.
