So... I've been using Google sitemaps for a while now, and it struck me
that Yahoo! and MSN/Live Search also probably have something similar.
Do they, and are they worth using?
Is it bad to use puretext ones? I currently do that. I don't see why I
should waste bandwidth with XML data. Do the other search engines use
different formats, so you need to make one sitemap per engine, or do
they use a common standard (be it XML or puretext)?
Also, what's the current marketshare percentage between the largest
search engines?
