“The gloves come off”, as we would say here in the U.S - in other words, a fight has begun. Competing specifications for content syndication, long thought a dead issue, have been revived by this post from DeWitt Clinton and response by Robert Scoble. DeWitt then follows up with another response, for a good ongoing discussion.
Atom may be a better specification - I’m not an engineer, so I can’t comment intelligently on it from that point of view. But, from a marketing perspective, let me say this:
Sony’s Betamax was a better technology than JVC’s VHS. Does anyone remember that battle?
I’m not claiming to be prophetic here. I’m just noticing that buzz and adoption of RSS has swamped Atom. Is that a guarantee of widespread adoption? It could be - only time will tell. I’d be wary of basing my business decisions only on the fact that Atom is a better specification, though.
