Aren't definitions fun. The difference in my mind between a
feed/microformat and 'scraping' is whether the relevant output format
was designed to be human readable (IE: html) or machine readable (XML,
csv, etc). Whether there is manual labour is unrelated in my mind.
It is often called "screen scraping" from back in the days that a
screen of information was drawn, and then we tried to pull information
from that screen based on the location of information. Re-intepreting
HTML like we are doing here is a bit different, but we are still talking
about taking a page intended to be read by a human (rendered by a
browers) and instead interpret it as data as input to a
program/database/etc.
