What's old (scraping) is new again (microformats)
You know, I think I fully realized why microformats seem so appealing and familiar to me:
But, I just remembered that a few summers ago, I wrote a bit for the O'Reilly book Spidering Hacks that anticipates the notion of a microformat.
If you happen to have the book (which I highly recommend), or can read it on Safari (which I also highly recommend), take a look at Hack #96: Making Your Resources Scrapable with Regular Expressions.
Granted, my proto-solution published there suggested using regexes and consistenly named HTML id attributes. So, I'm much more pleased with the microformat approach using CSS classes. And, I'm currently trying to write a general microformat parser using Python's HTMLParser class, which beats using regexes.
Just thought I'd share the revelation, and toot my own fledgling writing horn. :)
