For the third or fourth time, Alex Iskold has written a deep post on, what else, The Structured Web over at RWW that provoked me into writing a comment that is worth repeating here as a blog post. Thanks for helping me with material!
Here's what I say:
"Yeah, big, big data-matching problem. I am excited about the 'wisdom of crowds' effect creating some organic commonality of xml tags much like delicious tags. I could believe that xml from Amazon and B&N and Alibris might all contain an 'author' tag. I think this organic effect is liable to be much more far-reaching than deterministic microformats, if not as neat and tidy."
