I wrote the following several weeks ago when the RSS/Atom story first broke:
“I’ve followed Winer’s writings for some time. Five years from now he’ll have an introspective moment and realize he should have found a path to work with Google (who is simply supporting a /true/ open standard) instead of raising the battle cry for RSS.”
I credit Winer for figuring it out now rather than regreting it later. Unfortunately, it seems like he’s more interested in taking the “co-opetition” approach (that he often critizes MSFT for doing) to “merging” the standards. Fortunately for him, RSS has been around long enough and has enough mindshare that those “testing” feed syndication will likely support it first, and Atom if their test is successful.
