If you have thousands of pages, navigation structure can be quite complicated.
And if you have flash menu ?
With sitemaps search engines can more intelligently crawl the site.
What happens, when site structure changed ? Tortue for crawlers.
What happens, when important page changed deep inside structure ?
Google:
Sitemaps are particularly beneficial when users can't reach all areas of a website through a browseable interface. (Generally, this is when users are unable to reach certain pages or regions of a site by following links). For example, any site where certain pages are only accessible via a search form would benefit from creating a Sitemap and submitting it to search engines.
Sometimes crawlers pick up sitemap seconds after submission.
Sitemap concept introduced Google and then Yahoo, MSN joined - they do know, what doing.
Sitemaps for (at least for me) is
must - crawler comes, picks up single file and indexes all webpages by list.
When page is changed, made chenges in sitemap
lastmod parameter for page in sitemap.
No need to recrawl (maybe almost all site) to reindex changed page.
Frankly speaking - I didn't expect somebody arguing against sitemaps.
